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.

◦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.
◦The mounted filter (model MAN/MANY) with it’s outer frame can be easily mounted in our filter holder (model FH). For a filter with diameter 30mm outer frame please see lens holder (model LHF-30S) for your reference.

▶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.
▶Please refer to here for Wavelength Characteristic Data (Reference Data, EXCEL file format).

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).
▶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.

Strengthened glass

Glass can be broken under sudden heat effection. Sudden difference of temperature occurs inside of the glass, it is called thermal expansion and the tensile stress of the inside of the glass occurs. The glass will be broken when the stress is beyond machine strength. However, stress is offset, and glass becomes hard to be broken when there is a compression power in the inside of the glass even if tensile stress is caused by heat to glass.
Using this principle, heat strengthened glass was made out of compression stress forcibly in inside glass at the beginning of the process.
In the polishing process, a strengthened glass must be brought to a familiar softening temperature before to the forcibly cooling process. The inner of the glass is higher in density than the outside of the glass.
