SLM (마이크로 렌즈)
  • SLM (마이크로 렌즈)
  • 구면렌즈보다도 소경으로 집점거리가 짧은 렌즈입니다. 컴팩트화된 레이저 광학계나 내시경등의 극소광학계의 조명용 렌즈로서 사용할 수 있습니다.
Attention

▶The micro lenses has a spherical aberration and the focal length will vary depending on the wavelength. Please check the “wavelength characteristic of the focal length data” on our web-site. (Reference Technical Data)
▶There is a direction to put light on the plano convex lens. Please let the parallel light incident from the convex side always. This may increase the spherical aberration in reverse, the focused spot may enlarge and the image will appear out of focus.
▶Since the anti-reflective coating is not applied with the lens, the transmittance is about 90% due to the loss of reflection of the front and rear surface of the lens.
