Examples of Applications

LVF in a Fluorescence Micro Plate Reader

(Source: http://www.bmglabtech.com/en/technology/microplate-reader-technology/obj-51-934.html)

“The advanced [LVF] monochromators, having continually

adjustable wavelengths … and bandwidths … for excitation

and emission, have significantly increased performance over

conventional monochromators.”

“The high transmission and the outstanding blocking of stray

light give the CLARIOstar’s monochromator system filter-like

performance.”
