High Performance Dichroic Filter

Grand Unified Optics provides a standard product of high-performance dichroic filter with a diameter of 12.5mm and 25mm in packaged and unpackaged versions and a laser wavelength of 488nm-1064nm. The incident angle is 45°. The product has the characteristics of a steep transition from reflection to transmission, and the transition steepness is less than 1% of the laser wavelength. It is widely used in microscopic imaging, Raman spectroscopy, biochemical analysis instruments, life sciences, education and scientific research and other related fields. We can also offer custom coatings according to your requirements.

Material Fused Silica

Diameter Tolerance ＋0.0/-0.1mm

Mount Thickness 3.5mm

Substrate Thickness 2.0mm

Thickness Tolerance ±0.1mm

Surface Quality 60-40

Clear Aperture ≥10mm（Φ12.5mm), ≥22mm（Φ25mm)

Laser Damage Threshold 1J/cm2@532nm (10ns pulse width)

AOI 45°with a shift of≤0.20%/degree (35-55°) see MyLight for performance

Note Arrow on ring indicates preferred direction of propagation of light.
