特徴

• Surface quality is one rank lower than that of Spherical Convex Lens (SLB-P).
• Can be used 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 recommend this lens unless you want to use it for high-precision experiments with lasers.
• It is a biconvex lens that can greatly refract and shorten the focal length.
• 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 and spherical biconvex 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.
