Edmund Optics offers a wide variety of Laser Optics, including Laser Lenses, Laser Mirrors, Laser Filters, along with a variety of other components designed for laser use. Laser Lenses are designed to focus, homogenize, or shape laser beams. Laser Mirrors are ideal for beam steering applications. Laser Filters transmit or reflect a portion of the laser light. Laser Windows are used to transmit designated wavelengths or protect sensitive components or work areas from stray light.

Edmund Optics offers the world’s largest inventory of off-the-shelf optical components, which includes an extensive selection of stock optical lenses such as Achromatic Lenses or Aspheric Lenses. Many of Edmund Optics’ lenses are offered with a variety of coating options for the Ultraviolet (UV), visible, or Infrared (IR) spectrums.

Knight Optical offer a range of Stock Ball Lenses and Half Ball Lenses, for use within Fibre Lasers. As the name suggests ball lenses are completely spherical lenses mostly made out of High Refractive Index Glass such as Sapphire, and LASFN-9 Glass. The reason ball lenses are most commonly used is for their ability to focus light when leaving a fibre optic, so that it can therefore be used for a laser application. The key feature of ball lenses is their short back focal length allowing for precision coupling where size or space is a limiting factor in the system. Ball lenses are typically used in pairs with one lens acting as a collimator for the second to focus the light back into the coupled fibre. Where a more compact solution is required a half-ball lens is typically more suitable. We hold a large inventory of Ball Lenses. •Stock sizes from 0.5 5mm to 10mm diameter. •Custom sizes available to quotation. •Half Ball lenses also available.

Knight Optical can offer UV Fused Silica Lenses for Solid State Laser applications. UV FS is a prime choice for lenses in use with Solid State Lasers due to its consistently high transmission in the UV/VIS/NIR regions. This means that it can be used with a range of different laser types, such as Titanium-doped sapphire (tuneable to 660-1080nm) or Alexandrite (tuneable to 700-820nm) with very little change in performance. UV FS is comparable to N-BK7 or other similar optical glasses in its performance, having a very similar average transmission over the VIS range up to approximately 2000nm and a slightly lower refractive index. The Abbe constants of UV FS are also very similar to that of N-BK7, although slightly higher. Read PDF for full specification

Knight Optical We can offer Custom Moulded Aspheric Lenses for use with Laser Diode Collimators. Aspheric lens surfaces are used to correct spherical aberration (where the converging light from a lens does not have a common focal point, resulting in a distorted image) in lasers and imaging. Traditional spherical lenses cannot collimate light effectively because even small angles of incidence can produce spherical aberrations. This can mean that several components may be required to get the desired result. The non-spherical surface of an aspheric lens allows a single component to effectively focus or collimate even highly divergent emissions, potentially replacing a multi-lens system with a single aspheric lens. Therefore Aspheric Lenses that are moulded are ideal for use within laser diode-to-fibre coupling applications. For more information read PDF ….

Knight Optical can offer custom Rod Lenses for use within Optical Systems. We supply a range of custom & stock Rod lenses for a range of applications. All individually QA checked and metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Knight Optical supply precision optical components to customers with Optical systems. Rod Lenses are a special variant of cylindrical lenses so they focus light to a line. Rod lenses have an outside face that is polished and the ends are ground. Typical uses for rod lenses would be to generate a line image from a circular laser beam. Rod lenses can be cut at 45 degrees for use in beam steering and other similar applications.

The production of ophthalmic lenses requires different marking processes, e.g. technical engraving and branding for spectacle lenses as well as UDI marking for contact lenses. 3DMicromac offers ophthalmic marking solutions for laser engraving of all types of ophthalmic lenses, e.g. prescription and sunglasses, or contact lenses. All systems use UV lasers for permanent marking and guarantee Highest engraving precision Accurate contrast adjustment Reliable process stability Maximum throughput Top availability Flexibility in system configuration and Simple retrofitting. 3DMicromac‘s customers can choose between premium quality excimer laser systems and high quality maintenance free DPSS laser systems. Both are suitable for the production of technical engravings and visible branding on blocked and unblocked lenses, as well as contact lenses. The microMARK™ MCF excimer laser system generates the engravings by cold laser ablation of 193 nm UV radiation.
