Dichroic Mirror Beam Splitter

A reflected component and a transmitted component.

Dichroic mirror beam splitter. Laser beam combining or splitting optical system heat control and fluorescence microscopy are a few of the most common uses of dichroic filters. The coating is applied to low iron glass to minimize tint and the anti reflective coating on the backside eliminates a double reflection. The position of 50 reflection and transmission is used to characterize the dichroic mirror e g. 85 of diameter edge bevel.

Dichroics are available at all wavelengths with reflectivity typically reaching values greater than 98 and transmission typically exceeding 85. They highly reflect one specified spectral region while optimally transmitting another. The simplest design reflects short wavelength and transmits long wavelength. Dichroic beamsplitters mirrors are used as light guiding optics intended to reflect a specified range s of wavelengths and transmit a different specified range s of wavelengths at a specified aoi typically 45 degrees.

R 0 25 reflectance. Dichroic filters separate a broad spectrum of light into two components. Cube beamsplitters non polarizing part code. 20 to 80 damage threshold.

These hard coated dichroic filters are designed with regions of high transmission and high reflection that are separated by a steep edge. Most of chroma s catalog dichroics are intended for use at 45 degrees aoi if unsure please ask us. Dichroic beamsplitters are longpass and shortpass filters that are used at non normal angles of incidence. This is the typical approach when dichromatic or dichroic splitting mirrors are implemented.

0 3 mm face width at 45 adhesion and durability. Product description beamsplitter mirrors also known as transparent mirrors have an optical grade dielectric coating on the face of the mirror which reflects 40 of the light. The transmitted beam has a wavelength in the transmission band of the optic and the reflected beam has a wavelength in the reflection band of the optic.
