The LSC-70 camera is ideal for applications requiring IR sensitivity up to 2,200nm and real-time (30 fps) video performance. The LSC-70 boasts a wide spectral response (400nm – 2,200nm) and high resolution (700 TV lines) to resolve fine detail.

The two-piece design of the LSC-70 camera allows for convenient desk-top control of image enhancement features with precise, lockable controls. A ten-step grey scale test signal allows the user to quickly and correctly set the contrast and brightness on a monitor.

The front panel controls offer extended gain and black level offset ranges to allow maximum contrast for low contrast imaging. The GAIN adjust sets image whites to desired level to optimize contrast. In AUTO setting, the camera automatically tracks and adjusts whitest portion of picture to an internally factory preset level. In MANual, the camera maintains a fixed gain that can be set to desired levels through gain control adjustments.

The BLACK LEVEL control varies contrast level for darkest portion of the image. In AUTO setting, the camera automatically tracks and sets darkest portion of image to a black reference level. In MANual, the camera maintains a fixed black reference regardless of variations in image contrast. The camera provides an internally factory-preset black reference for both automatic and manual operation in PRESET, or the user can set contrast levels as desired in VARIABLE.

Additional adjustments include: bandwidth, aperture, stretch, gamma and polarity. Use of the bandwidth control in conjunction with aperture control will achieve optimum sharpness with minimum noise. A Stretch function provides a six-fold amplification of user selected grey levels for maximum contrast improvement. Gamma setting in the .5 position stretches signal in black and compresses whites to improve low contrast images, while Gamma in the 1.0 position provides linear grey scale reproductions. Polarity provides an inverted grey scale output to better view the darkest information in the image under low contrast conditions.
