These YAG lenses range in focal length from 20 to 150mm. They consist of either two or three air-spaced glass elements mounted in a metal cell. The lenses all have a 30mm clear aperture but they are recommended for use with beams not exceeding one inch in diameter. Two different designs are used - the 20, 30, 40, and 50mm focal length lenses have three elements, but the 60, 80, 100, and 150mm lenses use simpler two element designs. These lenses are Anti-Reflection coated with a high damage Narrowband Multilayer Anti-Reflection coating optimized to give less than 0.5% reflectance per surface at 1064nm.
These lenses are chromatically corrected so that a HeNe guide beam or a visible range video monitor beam will be in focus at the same position as the YAG beam.
Spot size or beam waist is inversely proportional to the numerical aperture at the effective beam diameter. The spot size given in the table is for a full aperture beam. Let us know your imaging requirements and we will be pleased to advise you on the appropriate lens for your application.
Since these lenses are often used with high power lasers we offer optional protective windows which can be attached to the focusing side of the lens. In the event of inadvertent back reflection of high energy beams into the lens it is likely that the window will absorb the incident energy and shatter preventing further damage to the lens itself. Protective windows are offered uncoated in packages of ten pieces. For optimum performance we advise that the protective windows be Anti-Reflection coated with our A46 V Coat at 1064nm.

The Laser Mech Lens Mounting System solves the problem of lens removal for replacement and inspection. By using a simple cartridge mounted lens inserted into a side slot in a permanently positioned manifold block, the problems of the traditional threaded, axially inserted lenses are avoided. This innovative mounting method allows removal and replacement of the lens in seconds with no readjustment of the optical alignment and without the removal, replacement or disassembly of any other part of the optical system.
Each assembly consists of a lens mount manifold block with very fine, adjustable lens centering screws and a spring-loaded, lens holder assembly to hold the lens. The lens holder contains all the seals necessary to pressurize the space beneath the lens for use with the Gas Jet Manifold.

ROLYN Mirror Mounts are designed to give the very best combination of economy and performance. There is no glass-to-glass contact. Clear aperture obscuration caused by the plastic mirror holders is minimal. These three holders form an adjustable rigid orthogonal kinematic mount for the mirror which resists vibration and handling. Black anodizing minimizes reflections. Mirrors are not supplied with the mount.

VERSATILITY - CLIPLITE, installed in display panel, is used with PCB mounted LEDs. Lenses remain attached to the display or panel door while the LEDs are fixed to the PCB. The lenses are ideal for use together with the CONXRITE connector assembly.
BRIGHTNESS - CLIPLITE utilizes fresnel rings to increase apparent brightness and viewing angle up to 180 degrees with either diffused or nondiffused LEDs.
PROTECTION - CLIPLITE helps prevent IC failures caused by electrostatic discharge (ESD). Introduction of EDS through an exposed panel mounted LED is capable of damaging or destroying a semiconductor. A CLIPLITE mounted LED helps guard components from ESD up to 16 kV while affording the LED physical protection.
INSTALLATION - CLIPLITE is inserted through panel opening, retaining ring is pressed into place. PCB mounted LEDs slide into lenses when the panel cover is closed or the PCB card is inserted into the case.
SPECIFICATIONS:
MATERIAL: Lense - Polycarbonate; Ring - Polypropylene (U.L. Listed Materials)

The GLO Series lenses are made from a unique thermoplastic material that diffuses a LED’s light output and dramatically reduces “hot spots”. The result is a clean, hi-tech glow that evenly distributes the light along the lens surface and can be viewed from nearly any angle. Currently, VCC offers the SMB 200, SML 190, CLB 300, and CLF 280 as part of the GLO Series. Custom design inquiries are welcome

Lens holders are designed to position miniature lenses over CCD/CMOS imagers with high degree of accuracy. Lens holder must keep the lens optic axis centered on the active area of the imager. It must also keep the lens axis perpendicular to the imager surface. Some lens holders also provide special features for holding IR cut-off filters and optical low-pass filters. Lens holders are precision-molded with special plastic materials.

Features
Kowa is the first lens manufacturer introducing a new generation of HD-Multi-Megapixel Day & Night CCTV lenses for IP-Day & Night cameras with more than 3 Megapixel resolutions.
The outstanding performance of the new HD-Multi-Megapixel Day & Night series is achieved due to a special mechanical design and the usage of aspherical lens technology. By using XD-glass (eXtra low Dispersion) and special coating technology these lenses provide crisp colour images in day time and crisp black & white images in night time (IR light) without refocusing. This advanced optical design easily corrects colour aberration and contributes to the birth of this excellent HD-Multi-Megapixel Day & Night series.
The HD-Multi-Megapixel Day& Night varifocal lens series is designed for 1/2" sensors with 2 different models. LMVZ3510-IR covers a focal range between 3,5 – 10mm with an maximum angle of view of 108° whereas LMVZ9020-IR covers a focal range between 9 – 20mm.
Kowa’s advanced HD-Multi-Megapixel Day & Night series will pave the way for High End IP-Megapixel applications in outdoor environment.
LMVZ3510-IR and LMVZ9020-IR are guarantee for HD-Multi-Megapixel resolution during day time and night time with a minimum focus shift.

Microscope objectives are ideal for use as focusing lenses for low power lasers such as HeNe and HeCd. We offer a selection of precision achromatic objectives covering a range of numerical apertures. They are housed in conventional microscope barrels and fitted with a standard RMS microscope thread. The lenses are Anti-Reflection coated.

Most microscope objectives are optimized for the same object-to-image distance. This allows objectives to be interchanged without refocusing. Most Melles Griot objectives have an object-to-image distance of 195 mm because long focal lengths are required to maintain both the same image plane (150 mm from the mounting shoulder) and good image quality. All objectives are achromatic and have industry-standard microscope threads for cross compatibility.
The visible, infrared, and infinite-conjugate microscope objectives from Melles Griot are achromatic (i.e., color corrected at 656.3 nm and 486.1 nm). The RMS mounting thread (0.8 inch, 36 TPI) matches the industry standard making these objectives compatible with non- Melles Griot microscopes. Color coding makes identifying objective power easy when numerical markings cannot be seen. Visible objectives are antireflection coated for 400 to 700 nm; infrared objectives are antireflection coated for 1300 to 1500 nm.

Astrodon® tru-balance filters are the first filters designed to match the sensitivity of modern CCD cameras. Using filters matched with the detectors greatly simplifies all aspects of deep-sky tri-color imaging. Benefits include shorter imaging times, G2V white point balance, balanced OIII nebula color, and pre-balanced RGB channels when using Kodak Blue Plus CCDs.
They are an outgrowth of over a year and a half of research, published in Sky and Telescope and presented at AstroImage and Imaging the Sky conferences. The narrowband filters, H a, SII and OIII, allow you to image when the moon is up, thereby extending the amount of imaging time you have each month. Since they are parfocal with the LRGB filters, you can easily focus on the L or C filter and then switch to the narrowband filter WITHOUT refocusing.
