61-6927-21 Aspheric Condenser Lens φ18mm Focal Length 12mm AGL-18-12P
Features
- Aspherical condenser lenses for illumination can emit light for illumination at a large divergence angle (focusing angle).
- It is used in high-magnification microscope illumination systems and optical systems that efficiently collect light from divergent light sources.
- A large divergence angle (focusing angle) of approximately NA0.5 has been achieved with a single lens by using an aspherical shape on one side.
- Available in a variety of outer diameter sizes, from compact with a small aperture to large-aperture lenses with a longer back focus.
- It can be used in a wide range from the visible range to the infrared range with a wavelength of 2 μm.
- B270 (R) is a registered trademark of SCHOTT AG.
- * When parallel light is incident from the back (plane) side, spherical aberration is large and light does not converge to one point.
- * Since an aspheric condenser lens is a single lens, the focal length varies depending on the wavelength.
- * Aspherical condenser lens is used for lighting.
- * This is not an aberration-free lens for laser focusing.
- * Since the lens is not coated with an anti-reflection film, the transmittance of the lens is less than 90% due to the loss caused by reflection of the front and back surfaces of the lens.
- * As this is a pressed product, there may be dents or scratches caused by sink marks outside the valid range.
