Features
- Surface quality is one rank lower than that of Spherical Convex Lens (SLB-P).
- Can be ***d for optical systems that do not require high surface quality, such as lighting or observation applications.
- Other than surface quality, the specifications are almost the same as the Spherical Convex Lens (SLB-P).
- I recomm*** this lens unless you want to *** it for high-precision experiments with lasers.
- A plano-convex lens with low spherical aberration.
- In addition to the no-coat product, three types of lenses with anti-reflection film are available in the visible, near-infrared and infrared ranges.
- * 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.
