SIGMAKOKI Plano Convex Lens (Synthetic Fused Silica) φ100mm Focal Length 200mm　SLSQ-100-200P

Feature

• A lens for laser experiments with a simple shape and slightly reduced spherical aberration.
• It can be used 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 used 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 depends 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 cause the spherical aberration to increase, which can cause the focus spot to increase and can cause blurred images.
• * The transmittance of the uncoated product is about 90% due to the loss caused by the reflection of the front and back of the lens.
