This light source box is guaranteed brightness (luminance), color (color temperature), and uniformity within the light emitting surface with high accuracy.
From nearly 50 years of experiences responded to various requests,
A new LED surface light source box was developed under the concept of “The BEST”, which achieved to have plentiful functions, reasonable price and appropriate specifications for users.
This is also used for a calibration or an evaluation (inspection) light source as the standard light source for camera adjustments such as white balance.
Functions equipped with High-End Model
- Specify the desired detailed brightness with using the numeric keypad.
- Brightness unit can be selected from 3 units at any time.
- DC lighting without flicker as the standard mode
- Frequency lighting by pulse mode reproduces the lighting environment by voltage flicker
- Always display the current illuminance (Sampling display function)
Pursuing basic performance while controlling price and size
- Luminance uniformity within the light emitting surface is 95% or more.
- Luminance feedback function monitors and corrects luminance. Correction accuracy is within 0.5%.
- Using high color rendering LED.
- Dimensions of the housing legs are designed to be fixed to an optical surface plate, etc.
- Weight is less than 5 kg.
- Reproduction range of luminance is 128 times (7EV).
- Recall the brightness and color temperature registered in advance.
- Color temperature can be switched.
- Device is functional and can be customized as required.
LSB-111WCRI series, which has a wide range of brightness and various functions, VLB-10FBW2-CRI and VLB-1411FBC-CRI, which are portable, lightweight and reasonable, are models that combine these good points.
