We offer a complete line of ND filters to reduce intensity of the visible light. This is an absorptive type of filter that reduces stray reflected light and reduces intensity of the light with minimal difference of transmission for visible wavelengths.

Details

◦The transmittance can be fine tuned and can offer light intensity adjustment. Moreover, with a multi-filter set up, ultra fine light intensity tuning can be realized.

Name	Absorptive Neutral Density Filter Unmounted (Visible) Square 30x30mm 40%
Weight	0.0060kgs
Standard Coatings Available	No
Guide	Different size, wavelength and deviation ratio which is not listed online or in our catalog is available as custom product upon the request. Absorptive ND filter placed near to a light-source can be broken by the sudden high temperature. The filter must be treated with thermal reinforcement for heat resistance.
Remark	-
Attention	Do not use with high power laser, the filter can be damaged. In that case, please try our Reflective type of ND filter (model FND). To obtain a better transmittance characteristic, the thickness of the filter can be changed. For this reason the thickness of each filter is different. For filter with thickness below 5mm, we recommend to use the mounted filter. (model MAN/MANY). The filter transmittance characteristic of each production lot is different. The outside wavelength properties of the adaptation wavelength may greatly vary in particular according to production lot. Please refer to reflective filter (model FND) if the use of wavelength is wider than a specified wavelength. ND filter does not have Anti Reflection coating so there is 4% reflection loss.
