Coloured Glass Bandpass Filter, Φ25mm, Transparent, CWL: 510nm, United Optical Technology Co., Ltd (CAT#: STEM-OP-4271-YJL)

Coloured Glass Bandpass Filter, Φ25mm, Transparent, CWL: 510nm, model 259110, is manufactured by United Optical Technology Co., Ltd.
Colored Glass Bandpass Filter refers to adding special elements during the glass melting process to absorb different spectral bands and transmit other spectral bands.
Precautions for use: Please wear finger cots when using, and do not touch the surface of the shortwave filter directly with your fingers to prevent residual fingerprints from affecting the light-passing effect of the shortwave filter. If the surface of the shortwave filter is dirty, use dust-free lens cleaning paper dipped in alcohol to wipe the lens surface. Do not wipe with cloth or paper with a very rough surface or water, otherwise the surface of the shortwave filter will be damaged.

Diameter: Φ25mm
CWL: 510nm
Filter Color: Transparent
Material: Coloured glass
Glass Model: KG5
Surface Accuracy: λ/2@633nm(25mm Area)
Parallelism: ＜1arcmin
Surface Quality: 40/20-60/40
Diameter Tolerance: +0.0/-0.2mm
