Product Details

Product Model: 61-6897-49
Product Brand: SIGMAKOKI CO., LTD.

Features

  • A lens for laser experiments with a simple shape and slightly reduced spherical aberration.
  • It can be ***d to focus laser light on a detector or for imaging experiments using a monochromatic light source.
  • It is a lens made of synthetic quartz that can be ***d with ultraviolet light below 350 nm and has high laser resistance.
  • It can be selected according to your specifications from a wide range of variations, subdivided by outer diameter size and focal length.
  • Chromatic aberration corrected achromatic lenses (DLB) are also available.
  • * Spherical plano-convex lenses have chromatic aberration, and the focal length dep***s on the wavelength.
  • * Plano-convex lenses allow light to enter.
  • * Be sure to allow parallel light to enter from the convex side.
  • * Doing the reverse operation will ca*** the spherical aberration to increase, which can ca*** the focus spot to increase and can ca*** blurred images.
  • * The transmittance of the uncoated product is about 90% due to the loss ca***d by the reflection of the front and back of the lens.
