Forms of Supply for optical Glass Filters

Filter Glass Types

1. Polished Filters
Filters can be supplied as polished rectangular plates or round discs with finely processed edges.
Upon request, products can be thermally strengthened and/or coated with protective or anti-reflective (AR) layers to enhance durability and optical performance.

2. Filter Glass with Processed Edges
Rectangular plates and round discs with matte surfaces and precisely processed edges, suitable for applications requiring safe handling and improved edge quality.

3. Filter Glass without Edge Processing
Rectangular plates and round discs featuring matte surfaces with unprocessed edges, offering a cost-effective solution for further customization or secondary processing.

UG Black and blue glass which permits the transmission of UV light.
BG Blue, blue-green and bandglass designed for selective wavelength transmission in imaging and analytical systems.
VG Green glass suitable for general optical filtering and contrast enhancement applications.
GG Yellow glass that enables infrared(IR) light transmission.
OG Orange glass which permits infrared(IR) light transmission.
RG Red and black glass designed for infrared(IR) light transmission.
NG Neutral density glass provides nearly constant attenuation across the visible spectrum.
N-WG Colorless glass with various UV cut-off wavelengths, allowing transmission of visible and infrared light.
KG Nearly colorless glass with high visible light transmission and strong infrared absorption.
FG Blue and brown colored glass designed for wavelength conversion applications in specialized optical fields
