Andover Color Glass Filters
Versatile spectral control through engineered absorption materials
Color glass filters provide a unique approach to wavelength selection through specially formulated glass materials that absorb unwanted light while transmitting desired wavelengths. Unlike interference-based filters, color glass filters achieve their spectral properties through the intrinsic absorption characteristics of their constituent materials.
Each filter is characterized by three key properties:
- Transmission Range: The wavelength region the glass is engineered to transmit
- Internal Transmittance: The percentage of light transmitted within the passband
- Cut-on/Cut-off Points: The wavelengths where transmission rises above or falls below 50%
Using high-quality optical filter glass that is precision polished on both surfaces, our color glass filters deliver excellent spectral consistency and sharp contrast across ultraviolet to infrared wavelengths, providing a robust and economical solution for applications requiring broad spectral filtering.
Color Glass Optics: Absorption-Based Spectral Control
Advanced Light Management Through Precision Glass Engineering
From standard bandpass solutions to custom heat-absorbing designs, our color glass filters combine excellent transmission characteristics with robust environmental stability to deliver consistent performance across a wide range of applications. Unlike interference-based filters, these filters achieve their spectral properties through the intrinsic absorption of carefully formulated glass compositions, offering an economical and durable solution for broad wavelength control.
