BUY PARABOLIC MIRROR SERIAL NUMBERS

Typical applications include spectrometer configurations, collimator and beam expanders. In addition to parabolic mirrors, o ur SPDT capabilities allow us to manufacture polynomial mirrors, plano mirrors, folding mirrors, complex cylindrical optics and aspheres. The weight of the glass can deform a thin mirror. the thickness is much less than 1/8th its diameter) then the mount must hold the mirror without deforming it. A parabolic (or paraboloid or paraboloidal) reflector (or dish or mirror) is a reflective surface used to collect or project energy such as light, sound. When combined with our world-class metrology lab, what you order is precisely what we deliver. A mirror mount is needed to hold the mirror during testing. Key Capabilities: Our multi-axis diamond-turning machines allow us to transform your ideas into solutions. Our mirrors are centre marked for ease of collimation.When your application calls for the ability to collimate light without spherical aberration, you may need an off axis parabolic mirror to focus broadband light sources.

We coat our mirrors with aluminium in a vacuum coating chamber and finish with protected coating of SiO2 which guarantees the highest longevity and efficiency of 93% reflectivity.Īll our mirrors have serial numbers as well as a complete report of its testing. Please go through this essay on Float Glass Mirrors. Thin glass blanks of float glass achieve thermal stability quickly. Float glass is a softer than other glass materials and consequently it can be polished to a great degree of accuracy and smoothness. In the near future we will be in a position to offer fused glass primary mirrors of 38 mm thickness. Whether your style is modern, industrial, midcentury or farmhouse inspired, we’ve got a decorative wall mirror to tie your space together.

If you want to customize a mirror, we also carry mirror frame kits. We offer Primary Mirrors made from Float Glass, thickness 25 mm. Our mirrors come in a variety of frame materials and colors, including rustic reclaimed wood, modern metal, glass, gray mirrors and more. The optical axis of an OAP mirror is parallel to, but displaced from the optical axis of the parent parabola. A conventional parabolic mirror is illustrated in Figure 2. A smooth surface provides a much better contrast at the eyepiece, and is especially beneficial for revealing fine detail on planetary surfaces. Off-Axis Parabolic Mirrors The reflective surface of an OAP mirror is a section of the parent parabola that is not centered on the parents optical axis (Figure 1). Apart from the Strehl ratio, we endeavour to produce an excellent smooth surface with no micro ripple or roughness. TECHSPEC® Ultrafast-Enhanced Silver Laser Mirrors Available. Effective Focal Lengths from 25 to 500mm. Low Group Delay Dispersion as Low as 0 ☒0fs 2. Ideal for Focusing Ti:sapphire and Yb:doped Laser Pulses. A Strehl ratio of 0.8 is good, 0.9 is excellent, 0.95 or better is outstanding. The meaning of PARABOLIC REFLECTOR is a concave mirror that has the form of a paraboloid of revolution so that rays emanating from the geometrical focus and. Ultrafast-Enhanced Silver Concave Laser Mirrors. The best opticians now use the Strehl ratio for specifying the quality of primary mirrors. The mirrors are frequently tested for accuracy of overall figure as well as for the smoothness of the surface.Īll our Primary Mirrors are guaranteed to a Strehl Ratio of 0.90 or better. All our primary mirrors are precision made and finished with hand figuring to a perfect parabola. We have a complete in-house production facility. Reflectivity and quality of aluminisation and protective coating.Īt Aperture Telescopes, we offer Parabolic Primary Mirrors in diameters of:Īll proudly Made in India, right here at our optics shop at Manesar, Gurgaon.Quality of reflecting surface, accurately parabolised, smoothness of micro surface,.The main considerations for purchasing a Primary Mirror are as follows: The performance of a telescope is mainly dependant on the quality of its Primary Mirror. All this guarantees the achievement of excellent quality of the optical surface with balanced edges, absence of zones and smooth surface. The Primary Mirror is also known as the Objective and is the heart of a good telescope. Our parabolic telescope mirrors are made using a unique precision computer-controlled method and the whole manufacturing process is controlled by interferometric tests. The ‘Primary Mirror’ is the principal light-gathering surface of a reflecting telescope.
