GJB golden glass

Colored optical filter (golden glass)

Made of special colored glass
Spectral absorption of dopants in materials to specific bands
Transmission band 400 ~ 2500nm
This kind of filter is not suitable for use under strong laser conditions

GJB golden glass
Gjb510 golden glass transmittance:

 Transmittance wavelength characteristic reference
It is equipped with coated long wave pass filter and narrow-band filter

Undertake samples and mass customization
If you need supporting installation and adjustment support, please contact us

Colored optical glass belongs to absorption glass
Maximum transmittance and cutoff wavelength
It depends on the actual thickness of the glass
Attention shall be paid to the selection

High power laser cannot be used in the absorption wavelength range
High energy pulsed laser
Antireflective film is not evaporated on both sides
There is reflection on the front and back
The maximum transmittance is about 90%

To reduce surface reflection, antireflective coating can be applied as required
