04 NX 025 High-index Planoconcave Laser Lens
COMAR Optics
Lenses in high-index glass (n = 1.785) have only 55% of the spherical aberration of equivalent BK7 lenses, and can be very efficiently AR coated with a single-layer coating. Beam expanders etc. can therefore be made with near diffraction-limited performance and very high transmittance and suitable for high powers, having no cemented ...

Material: BK7
Diameter: 2.5 mm
Focal Length: 4.0 mm
Edge Thickness, Te: 1.0 mm
Lens Type: Plano-Concave
10 NS 06 UV-Silica Concave Lens
COMAR Optics
This range provides negative lenses for use down to 170nm in the UV, or for hostile environments requiring greater thermal, chemical or radiation resistance than ordinary glasses. UV fused silica also exhibits very low fluorescence. AR-coated lenses are offered for improved UV transmittance.

04 NT 025 Quality Concave Lens
COMAR Optics
Negative lenses form a reduced virtual image of a real object (as in door viewers).  However, if inserted in a system such as a microscope upstream from an image plane, the image will be magnified and projected further. Such a lens is known in microscopy as a tube-length correction lens and in astronomy as a Barlow lens. We ...

237 PH 152 Large Condenser Lens
COMAR Optics
These planoconvex condenser lenses are optically polished with moulded edges.  Except for 568 PQ 254 they are in low-expansion borosilicate glass (Suprax) and have excellent thermal shock resistance.  This material contains some striae and bubbles,but these are not normally significant for condenser applications.

06 VB 06 Biconvex Lens
COMAR Optics
These crown glass biconvex lenses are suitable for almost all singlet lens applications. The biconvex form is preferred when the conjugates are roughly equal; for focusing collimated light see our range of planoconvex lenses. Most lenses are also stocked in three different AR coatings covering from the visible out to telecoms IR ...

Plano-Concave Spherical Lens
Atoptical Co., Ltd
Plano-Concave Lenses are the best choice where object and image are at absolute conjugate ratios greater than 5:1 and less than 1:5 to reduce spherical.Plano-Concave lenses bend parallel input rays so they diverge from one another on the output side of the lens and hence have a negative focal length.The spherical aberration of the ...
