Features
- A square filter for dimming the light of a YAG laser (1064 nm).
- Since it is an absorption type, stray light due to reflection is small, and the wavelength characteristic of transmitted light does not change significantly due to dimming.
- Since the transmittance is finely divided, the light can be dimmed to various light levels.
- Furthermore, by combining multiple filters, subtle light adjustment is possible.
- If an absorbent fixed ND filter is placed near a light source, the filter may break due to sudden temperature changes.
- If the filter is subjected to heat strengthening treatment, the filter will not break easily even if the temperature rises.
- If the filter is thermally tempered, the dimension will be large and may exceed the tolerance range.
- * Cannot be ***d for high power laser.
- * There is a risk of damage if ***d.
- * Use a reflective ND filter (FND) for high power laser.
- * Since the transmittance characteristics are given priority, the filter thickness is adjusted to satisfy the transmittance performance.
- * For this reason, the thickness of each filter is different (6 mm or less).
- * Use a filter with a frame (MAN) when the thickness needs to be constant.
- * The transmittance wavelength characteristics vary dep***ing on the manufacturing lot.
- * In particular, the wavelength characteristics outside the applicable wavelength may differ greatly dep***ing on the manufacturing lot.
- * Use a reflective filter (FND) if the wavelength range is wider than the specified wavelength range.
- * The ND filter does not have an anti-reflection coat, so the reflection is about 4%.
