Specifications and Product Details:

Band pass filters, which allow required ranges to pass through selectively

Long pass filters, which block unwanted shorter wave ranges
Short pass filters, which block unwanted longer wave ranges
Neutral density filters, which have a virtually constant transparency especially in the visible range
Conversion filters, which due to their spectral range increase or reduce the colour temperature of radiation sources

Materials

Basic glass
Ionically coloured glass
Colloidally coloured glass

Applications
Optical glass filters are used in a host of different applications. Optical glass filters are significant components in industrial measurement, control and regulation technology through analytical measuring methods in production, research and development all the way to environment protection and medicine with which to permit or block the transmission of specific spectral ranges.

Filter Glass Types

UG Black and blue glass which permits the transmission of UV light
BG Blue, blue-green and bandglass
VG Green glass
GG Yellow glass which permits IR light transmission
OG Orange glass which permits IR light transmission
RG Red and black glass which permits IR light transmission
NG Neutral glass with virtually constant radiation weakening in the visible range
N-WG Colourless glass with different cut-off positions in the UV range and which allows IR and visible light transmission
KG Virtually colourless glass with high transmission of visible light and absorption of radiation in the IR range
FG Blue and brown coloured glass (conversion glass)
