Dichroic Mirror Beam Splitter

Thorlabs dichroic mirrors beamsplitters consist of a hard ion beam sputtered coating deposited on a uv fused silica substrate providing excellent transparency over the operating wavelength range virtually zero autofluorescence and a low coefficient of thermal expansion making them an ideal choice for applications from the uv to the near ir.

Dichroic mirror beam splitter.

0 3 mm face width at 45 adhesion and durability. Dichroic beamsplitters alluxa optical filters high performance dichroic filters and polychroic filters. Dichroic filters separate a broad spectrum of light into two components. A reflected component and a transmitted component.

The simplest design reflects short wavelength and transmits long wavelength. 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. Dichroics are available at all wavelengths with reflectivity typically reaching values greater than 98 and transmission typically exceeding 85. Laser beam combining or splitting optical system heat control and fluorescence microscopy are a few of the most common uses of dichroic filters.

This is the typical approach when dichromatic or dichroic splitting mirrors are implemented. Most of chroma s catalog dichroics are intended for use at 45 degrees aoi if unsure please ask us. The position of 50 reflection and transmission is used to characterize the dichroic mirror e g. Dichroic beamsplitters are longpass and shortpass filters that are used at non normal angles of incidence.

488 nm to 1550 nm polarization. R 0 25 reflectance. 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. 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.

Figure 1 depicts a dichroic mirror beamsplitter being used to combine a transmitted beam blue with a reflected beam red. 20 to 80 damage threshold. The coating is applied to low iron glass to minimize tint and the anti reflective coating on the backside eliminates a double reflection.
