The main features of accurately and conveniently analyzing brightness/chromaticity uniformity: the V(λ) matching of
high-precision
optical systems can reach national standard level or first-class level.

High dynamic range
adopts high dynamic range imaging technology (HDR), which can accurately measure measurement objects with large brightness differences.
The widest possible brightness measurement range is 0.001~200, 000cd/m2 (depending on the order).
High stability.
Some models adopt professional TE refrigeration and temperature control technology to achieve higher stability and repeatability.
High imaging quality
with large-diameter/high-quality internationally renowned objective lens enables measurement from macro to infinity.
