Product Details

Product Model: 61-6877-12
Product Brand: SIGMAKOKI CO., LTD.

Features

  • A round filter for dimming visible light.
  • 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%.
