Construction and Properties of Delta’s Filters
Advantages of Delta’s Linear Variable Filters
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.”
