Light source LSB-111TWR series with adjustable brightness over a wide range.
LSB-111WR Series
It is an ideal light source for calibration, adjustment, and inspection, capable of outputting a wide range from low brightness to high brightness as a standard light source.
1: This is a light source that can output finely from low brightness to high brightness. 2: Thanks to internal automatic correction, it consistently outputs stable brightness, eliminating the need for regular maintenance. 3: This light source has high brightness uniformity (low brightness variation), making it ideal for various calibrations, adjustments, and inspections as a standard light source. 4: External control is possible via serial communication. 5: By connecting to our luminance meter (LC-5), it is possible to calibrate the internal brightness sensor of the light source, simplifying the maintenance of the luminance box.

basic information
This light source is a diffused light source for the adjustment and inspection of various sensors such as cameras, CCDs, and exposure meters. The brightness value can be set arbitrarily over a wide range and is displayed. It features three modes: an arbitrary selection method that allows for the selection of any brightness, a pitch variable method that can vary brightness at any pitch (from 0.1 LV to 1.0 LV), and a memory selection method that can store and recall 99 arbitrary brightness values. Model Output Brightness Range (cd/m²) LSB-111T2/B 2.24 ～18300 LSB-111TWR/B0 0.14 ～18300 LSB-111TWR/B2 0.035 ～18300 LSB-111TWR/B4 0.009 ～18300 LSB-111TWR/B418 0.009 ～36600 *Customization of special specification light sources such as brightness value, color temperature, and brightness area is possible.
