61-6906-57 Biconvex 렌즈 BK7 와 250.6mm 초점 거리 SLB-40B-250PM
기능
- By making both sides convex, this lens can efficiently refract light in a small space and collect more light.
- Use this function when you want to collect collimated light at the shortest distance possible or when you want to collect as much light as possible from the emission point.
- 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 the wide variety of subdivided by outer diameter size and focal length.
- Chromatic aberration corrected achromatic lenses (DLB) are also available.
- * Spherical biconvex lenses have chromatic aberration, and the focal length depends on the wavelength.
- * The spherical aberration of a biconvex lens is larger than that of a plano-convex lens, and the focus spot may not be concentrated at one point.
- * 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.
