This spectral dichroic and filter plate will allow you to scan a variety of filters and dichroics: six 13 mm round filters, two dichroics sized up to 27mm x 19mm, two dichroics sized up to 35mm x 15mm, and four rectangular filters sized up to 30mm x 12mm. The plate will accommodate mounted and unmounted filters, and, holds dichroics at the required 45 degree angle for proper functioning. Using the MARS data analysis software full spectrum (220 to 1000nm) plots can be displayed in OD or percent transmission. It’s a great accessory for turning your microplate reader into a high volume optical scanner for R&D, QC, and other related work.
