Colour Glass filters are useful for selective wavelength absorption and therefore achieve high out of band blocking.
Also, these filters are durable, stable, and widely used in imaging, spectroscopy, and fluorescence applications.
Compared to coated filters, the colored glass filters offer excellent environmental stability and cost-effectiveness.
Advantages of the longpass filters:
- High optical performance and stability
- Excellent environmental adaptability
- High transmittance and precise cutoff wavelength
- High cost-effectiveness
- Customization options
Applications of Colored Glass Longpass Filters:
Fluorescence Microscopy
Spectroscopy
Machine Vision
Photography & Imaging
Laser Systems
FAQS:
1. What is a colored glass longpass filter?
A colored glass longpass filter is an optical filter that transmits longer wavelengths of light while blocking shorter wavelengths, using absorptive colored glass material.
2. What materials are used?
Also, they are usually made from high-quality optical colored glass with stable spectral characteristics.
3. What wavelength ranges are available?
Commonly from UV to near-infrared regions.
4. Can they be customized?
Yes, shapes, sizes, and cut-on wavelengths can be tailored to meet specific requirements. Therefore, if you need it, please contact us.
