Dichroic Beamsplitters

Delta Optical Thin Film is one of the few companies that can produce low-bending dichroic beamsplitters

Delta Optical Thin Film’s dichroic beamsplitters feature high transmission band, high reflection band and edge steepness.

DCLP — Long Wave Pass Dichroic
DCSP — Short Wave Pass Dichroic

These single-edge dichroic beamsplitters feature:

• Can be designed to have a low bending.
• Ultra-Hard-Coated filters.
• Scratch/Dig Optical Surface Specifications 60/40 (TopPride™), else 80/50.
• Standard dimension is a plate 26 mm x 36 mm x 1 mm — other dimensions on request.
• The wavelength given in the denomination is typically the edge wavelength where the transmission of the filter has reached 50% of the average transmission level.
• The data sheets show typical transmission curves for unpolarised light and an AOI=45°.
