Line scan cameras made in Iran

This monochrome line-scan camera has pixels 14 μm wide and 200 μm tall, so each one collects roughly 14 times the light of a 14 μm square pixel. That makes the RA-LSC-0511 a good match for spectrometers and laser-line sensing, where light is scarce and moderate spatial resolution is enough. The CCD has 2,048 pixels over about 28.7 mm and reads 950 lines/s. There is no electronic shutter, so it works best under steady, continuous light.

• Grating-spectrometer detector
• Laser-line position sensing
• Beam intensity-profile measurement
• Back-lit shadow width gauging

When you measure faint light, what matters most is being able to collect it for a long time. The RA-LSC-0526 lets you set exposure anywhere from 1 μs to 35.5 minutes, and its pixels are 7 μm × 200 μm. The linear CCD has 3,000 pixels over 21.0 mm and covers 400 to 900 nm. A 16-bit ADC converts the signal, the dynamic range is 320:1, the line rate is 325 lines/s and the maximum pixel frequency is 1 MHz.

• Visible and near-infrared spectrometers
• Measuring very weak emission
• Raman and fluorescence spectroscopy
• Laser-beam position sensing

When the object is wide and you don't want to give up detail, 7,500 pixels make the difference. The RA-LSC-0532 is a linear CCD camera with 7,500 pixels of 7 μm × 7 μm (2 × 3,750) on a 52.5 mm sensor, giving better than 0.1 mm per pixel even over wide fields. We built it for width gauging on conveyors and for scanning sheet, web, documents and film. It runs at 1,050.5 lines/s with a 16-bit ADC, and its 400 to 1000 nm response covers both visible and near-infrared light.

• Conveyor width gauging
• Sheet and web surface inspection
• Document, drawing and film scanning
• Near-infrared inspection

Bigger pixels mean more light in less time. The 14 μm × 14 μm pixels of the RA-LSC-0551 have four times the area of a 7 μm pixel, so they collect more signal for the same exposure. We built this camera for continuous measurement of width, thickness and edge position on production lines. The CCD has 2,048 pixels over 28.672 mm and reads 1,905 lines/s. It has a 6000:1 dynamic range, a 16-bit ADC and a 400 to 1000 nm spectral response.

• Width gauging on conveyors
• Sheet and strip thickness gauging
• Scanning moving objects
• Near-infrared inspection

Many line-scan cameras respond only from 400 nm up. The RA-LSC-0553 starts at 350 nm and runs to 900 nm, so you can also inspect with blue and near-ultraviolet light. Its sensor has 5,150 pixels of 7 μm × 7 μm over 36.05 mm, and it is designed for precise width and thickness gauging of sheet and web. It runs at 951.5 lines/s with a 16-bit ADC, and exposure is adjustable from 1,051 μs to 14.5 minutes in 1 μs steps.

• Precision width gauging
• Sheet and strip thickness gauging
• Surface scanning and defect inspection
• Blue and near-ultraviolet lighting

This color camera has three separate sensor lines, one each for red, green and blue. Each line has 5,363 pixels of 8 μm × 8 μm over 42.904 mm, so every point on the object is measured directly in all three colors. We recommend the RA-LSC-0718 for color measurement and sorting on conveyors and for inspection on printing lines. It runs at 1,020 lines/s with a 10670:1 dynamic range and 8-bit output, and its 400 to 700 nm response covers the visible band only.

• Color sorting of products
• Print and color inspection
• Document and artwork scanning
• Color scanning on conveyors

When an object moves fast or vibrates, its edges usually smear in the image. We built the RA-LSC-0751 for exactly that case: its electronic shutter cuts the exposure down to 1 μs, independent of the line rate. The sensor has 2,048 pixels of 14 μm × 14 μm on a 28.672 mm active length and runs at 2,376 lines/s. Spectral response is 400 to 1000 nm, and the 6000:1 dynamic range is captured by a 16-bit ADC.

• High-speed width gauging
• Thickness gauging of vibrating objects
• Surface scanning of moving objects
• Operation under intense illumination

The RA-LSC-1103 has a small sensor with very fine pixels: 1,500 pixels at a 5.5 μm pitch on an 8.25 mm active length. Each pixel is 64 μm tall, so it still collects enough light despite its narrow width. We recommend it for laser thickness gauging, width measurement in small fields of view, and compact spectrometers covering 300 to 1000 nm. The line rate is 641 lines/s, with a 16-bit ADC.

• Laser thickness gauging
• Width measurement in a small field
• Compact UV-VIS spectrometers
• Beam position and alignment sensing

Tall 14 μm × 200 μm pixels are the defining feature of the RA-LSC-1205, and they are why it performs well in weak light. The sensor has 2,048 pixels on a 28.672 mm active length, responds from 350 to 1100 nm, and accepts exposures from 3 μs to 35.5 minutes. The line rate is 951.5 lines/s and the dynamic range 400:1. We offer four versions, with a 16-bit or 12-bit ADC and an FPGA or microcontroller.

• Visible and near-infrared spectrometers
• Laser-line position sensing
• Shadow-based width gauging on conveyors
• Very low-light measurement

We built the RA-LSC-1209 for lines where sheet or web material passes under the camera at high speed, and it runs at 7,945 lines/s. The sensor has 2,048 square pixels of 14 μm × 14 μm on a 28.672 mm active length and reads each line in about 126 μs. The 2000:1 dynamic range is captured by a 16-bit ADC. Spectral response is 400 to 1100 nm, and the camera operates from -25 to +65 °C.

• High-speed sheet and web surface inspection
• High-speed width gauging
• Thickness gauging of moving products
• Near-infrared inspection

With 2,500 pixels on a 13.125 mm active length, the RA-LSC-1254 records spectra in very fine detail. Each pixel is 5.25 μm wide and 64 μm tall. We designed it for UV-VIS spectrometers and laser gauges that need to locate a position to better than one pixel. It offers 300 to 1000 nm spectral response, a 16-bit ADC, a 400:1 dynamic range and 385 lines/s.

• Laser thickness gauging with sub-pixel precision
• Back-lit width measurement
• UV-VIS spectroscopy

If your spectrometer works with weak signals, this is the camera we built for it. The RA-LSC-1304 is a CCD line-scan camera with 3,648 pixels, each 8 μm wide and 200 μm tall. Spread the 350 to 1000 nm band across its 29.184 mm array and each pixel sees about 0.18 nm of the spectrum. Exposure time can be set as long as 71 minutes.

• High-resolution spectrometers
• Raman and fluorescence spectroscopy
• Luminescence and very weak light
• Visible and near-UV absorption

Speed is what this camera is about. The RA-LSC-1402 reads 27,625 lines per second, one full line every 36.2 μs. The trade-off is a small pixel count: 256 large pixels over 16.248 mm. It is a good fit for position and edge sensing, object counting and laser-spot tracking on high-speed lines.

• High-speed position and edge sensing
• Laser-line and light-spot sensing
• Fast spectroscopy at moderate resolution
• Presence detection and object counting

We built the RA-LSC-1707 for jobs where fine detail matters. This monochrome line-scan camera has 7,450 pixels of 4.7 μm over 35.015 mm and reads up to 1,968 lines/s. Its main work is width gauging, thickness gauging and surface inspection on medium-speed lines. The dynamic range is 1800:1, read by a 16-bit ADC.

• Continuous width gauging on conveyors
• Thickness gauging by shadow
• Object scanning and surface inspection
• Document and drawing scanning

This color camera has three separate sensor lines for R, G and B, each with 2,700 pixels of 10.5 μm over 28.35 mm. Large pixels mean more light per line, and that is what lets the RA-LSC-2253 run at 2,990 lines/s. We recommend it for color inspection of paper, textiles and film, and for color sorting on medium-speed lines.

• Color sorting on conveyors
• Print and color inspection
• Color web and sheet inspection
• Color document scanning

Sorting produce and inspecting color on a production line takes both detail and speed. The RA-LSC-2566 has three 5,340-pixel lines for R, G and B and runs at up to 4,536 lines/s. Data goes over USB 3.0 at 600 Mbit/s, and the camera needs an external 6 to 8 V DC supply. The longest exposure is 20 ms, so this camera is built for bright, moving scenes.

• Color sorting of agricultural produce
• Color defect detection on production lines
• Color scanning of documents and drawings
• Reading color codes and barcodes

If you need detailed color images of documents, objects or printed samples and your line is not especially fast, the RA-LSC-2717 is a good fit. Its sensor has three color lines of 7,500 pixels each, with 4.7 μm pixels over a 35.25 mm active length. The camera captures up to 1,068 lines/s and sends data to the PC over USB 3.0 at 3.2 Gbit/s. It runs from an external 7.5 to 8.5 V supply.

• Color-assisted width measurement on conveyors
• Color scanning of objects
• Document and drawing scanning
• Print and packaging inspection

Scanning documents, drawings and flat surfaces in very fine detail is what we built the RA-LSC-2950 for. Its 6 × 10,680 linear CCD gives 10,680 pixels per color channel on a 4 μm pitch over 42.720 mm, with a 7000:1 dynamic range. The line rate goes up to 760 lines/s, and exposure is adjustable from 1,315 μs to 14 minutes in 1 μs steps. That puts this camera in scanners and static or slow-moving stations, not fast production lines.

• Document and large-format drawing scanning
• Artwork digitization
• Width measurement on conveyors
• Color inspection of slow-moving surfaces

When you don't need color but fine detail matters, the monochrome RA-LSC-2950 is the one to use. It uses the same linear CCD as the color version (2.8 μm × 4 μm pixels) over the same 42.720 mm active length. Here two interlaced sensor lines are read side by side, so each image line has 21,360 pixels over that same length. Dynamic range is 7000:1, the ADC is 3 × 8 bits, and the camera captures up to 760 lines/s with exposure from 1,315 μs to 14 minutes. Its main jobs are static film and text scanning, and width and edge gauging at resolutions finer than 50 μm.

• Film and negative scanning
• High-resolution text scanning
• Width and edge gauging
• Scratch and crack inspection on flat surfaces

We built the RA-LSC-3753 for width and thickness gauging and spectral recording, especially where light is limited or the wavelength falls outside the visible range. Its linear CCD has 2,088 square 14 μm pixels over a 29.232 mm active length and responds from 300 to 1100 nm. The output goes through a 16-bit ADC, and besides 480 Mbit/s USB the camera also has an analog output. Line rate goes up to 940 lines/s, and exposure is adjustable from 1.064 ms to 35.5 minutes.
