Detailed

Custom Dichroic Rainbow Optical Glass Filter

Felix Glass dichroic optical filter is a precision optical flat substrate coated with multi-layer vacuum sputtering interference film. The special coating creates obvious iridescent rainbow color shift when viewed from different angles, and realizes professional light beam splitting, wavelength filtering and spectrum separation functions.

We adopt high-transmittance N-BK7 optical glass as standard substrate, fused silica alternative is available for high temperature working environment. The multi-layer dichroic coating features stable spectral performance, scratch resistance and long service life, perfectly matching optical equipment continuous working demands.

Core Product Advantages

Professional multi-layer interference coating realizes accurate light spectrum splitting, separate transmission and reflection bands as customized requirement.

Unique rainbow iridescent visual effect, widely suitable for both industrial optical equipment and decorative lighting projects.

High light transmittance on target wavelength, low stray light interference, stable optical performance without spectral drift.

Full customization support: outline size, glass thickness, split wavelength spectrum, edge craft and coating formula.

Hardened anti-scratch coating layer, resistant to daily friction and long-time continuous operation.

Each finished dichroic glass will pass full spectrum testing and dimensional inspection before delivery.

Custom Processing Options

1. Shape Customization: Custom square, rectangle, circular wafer and irregular special outlines per customer drawing.

2. Spectrum Customization: Adjustable transmission & reflection wavelength band to match laser, stage light or detection equipment.

3. Thickness Customization: 0.5mm to 5mm optional, strict thickness tolerance ±0.01mm.

4. Edge Treatment: Raw edge, chamfer polished edge, light-absorbing blackened edge for anti-stray-light assembly.

5. Coating Customization: Single-sided or double-sided dichroic interference coating with customized rainbow color spectrum.

Typical Application Scenarios

This dichroic rainbow optical plate is widely used in multiple optical industries. It acts as core beam splitter component for stage color lighting equipment, and serves as laser beam splitting window for industrial laser systems. Besides, it can be equipped on spectral analysis instruments, laboratory optical experiment platforms, machine vision detection modules, as well as creative decorative lighting and art installation glass substrates.
