guide:

·Filters other than specifications and sizes can be provided.

reference resources:

·"Blue glass filter" is also commonly known as color glass filter.

be careful:

·The transmittance curve is the measured value of the sample and may vary with the manufacturing batch.

·During thermal strengthening treatment, the filter will expand. Please note that the overall dimension tolerance of the filter after thermal strengthening treatment is ± 0.2mm.

·When checking the optical path and adjusting the optical axis, be sure to wear laser protective glasses.

Blue glass It belongs to a kind of optical filter. The so-called optical filter is mainly used to eliminate infrared light and trimmed light. Because the blue wavelength has higher penetration rate, it has better penetration than the red orange glass filter, and can block the light with the spectrum falling at 640 ~ 650nm. It can be used in optical instruments or detection instruments that need to correct the color or show blue and need low reflection Such as video lens filter, automatic optical inspection (AOI), optical instrument, inspection instrument, etc.
