Manufactured Optical Colored Glass Filter

 What is a colored glass filter? 

The colored glass filter is an vital optical component which is made by colored glass. It allows some specific wavelength to pass through.

And also it blocks other ranges of wave length.

Compared with other coating filters, the colored glass filter relies on the material of colored glass.

It is considered by the absorption and transmission properties of the color glass.

Classification of colored glass filters

According to the different application scopes, color filters can be classified as long-pass filter, band-pass filter and short-pass filter.

The characteristics of colored glass filters

• Spectral selectivity: It can achieve functions such as long-wave pass, short-wave pass, and band-pass.
• High Stability: The absorption characteristics of optical glass do not easily deteriorate due to environmental changes.
• Durability: Resistant to high temperatures and humidity, and does not age easily.
• High cost-effectiveness: Compared to optical coated filters, colored glass filters have a simpler manufacturing process and lower costs.

  Application: 

• Optical Instruments:

Spectrometer, spectrometer, fluorescence detection system.

• Industrial Inspection:

Photoelectric sensing, environmental monitoring, quality inspection.

• Medical and Research (Medical & Research):

Fluorescence imaging, life science experiments.

• Photography & Imaging:

Color control, image contrast optimization.

• Lighting & Display:

Stage lighting, signal lights, display equipment.

 

Selection Guide

When choosing colored glass filters, the following factors should be given priority consideration:

•  Central wavelength (abbreviated CW)
• Full width at half maximum (FWHM)
• Peak transmittance (Tpk)

Different colored glasses will absorb certain wavelengths of light while allowing other wavelengths to pass through.

It is widely applied in laboratory optical systems, photography imaging, spectral analysis, as well as various detection and lighting systems.
