Before production begins, the specifications of the optical filter must be defined. This includes the wavelength range, bandwidth, transmission requirements, size, and shape. Simulation software is often used to model the filter's performance and optimize its design.

The substrate material, which can be Glass, UV Fused Silica or Silicon is prepared. The preparation involves cutting the substrate to the required size and shape and then grind & polishing it to achieve desired thickness and surface quality.

The deposition of optical coatings is the process of applying dielectrics layers of materials onto a substrate, to modify how it reflects or transmits light. This is primarily achieved by creating thin-film interference, where light waves interacting with the different layers either cancel each other out (destructive interference) or combine (constructive interference).

Using spectrophotometers (Cary5000) measure the transmission and blocking features to ensure the filters compliance with design specifications.

• Checkable Range : 175-3300 nm

Uses thin rotating diamond blades to saw through the material. Cut the raw filter piece (60x60mm to 80x80mm) into smaller filters.

• Minimum Cut Size : dia5mm or 3x3mm
• Maximum Cut Size : 58x58mm or 78x78mm

Upon request, optical filters are being assemblied into different mechanism.

• Unmounted
• Threaded / Non Threaded Mount
• Filter Cube / Filter Wheel
