Product Model: 61-6887-26
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.
- A lens made by BK7 for the visible to near-infrared range.
- Three types of lenses with anti-reflection film are available in the visible, near-infrared and infrared ranges.
- 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.
