UV Sharp Cut Filters

Compared to interference filters, this glass filter has a steep slope from the visible light. In addition, it is less affected by the angle of incidence and absorbs ultraviolet rays effectively.

Explanation of a sign excels very much excels
a little inferior. inferior

1)Tempering can be customized depending on your application.
(To improve heat resistance or high impact resistance)
Note: After the tempering process spectral characteristics may slightly shift from original one.
2)Spectral characteristics shown on this website are nominal values. The transmission curves can be calculated for a given thickness and are for reference purpose only.
3)Spectral characteristics shown here are measured at room temperature (25degrees C, 50% relative humidity)
4)Please consult us about applications and ambient condition.
