The mirrors for all of our models have an interferometric test certificate, which guarantees high quality. Focal ratio: f/4.5 A meniscus mirror enables you to enjoy crystal clear, sharp images, much faster than a conventional mirror. Welcome to Lockwood Custom Optics, Inc. Information / Contact: In-Stock Mirrors: Clients Projects: FAQ: Customer Comments History & More: Online Articles: In The Shop This shape is achieved by bending ("slumping") a thin flat blank in a kiln. Disassembled: heaviest part - 12kg, largest part: 51x51x35cm, Aperture: D=300 mm (12") Mirrors. conical cross-section mirrors. Weight: assembled - 39kg Interferometric test with a certificate: Yes This is because we complete them to the highest standards. Disassembled: heaviest part - 16kg, largest part: 58x58x36cm, Aperture: D=355 mm (14") What is a meniscus mirror? All of our products, as well as our finished telescopes, go through a number of quality assurance tests, to guarantee an unforgettable viewing experience. A meniscus mirror is a concave mirror with a convex backside; a telescope mirror featuring a constant thickness. A meniscus mirror performs better than a conventional mirror, after a shorter cooling period and without the need of cooling fans. Mount: High quality, wooden, alt-azimuthal dobsonian mount Weight: assembled - 30kg Handcrafted Custom Telescopes and Precision Optics, Aperture: D=400 mm (16") Focal length: F=1680 mm We produce handcrafted telescopes and optical mirrors since 2006. Focal length: F=1500 mm The optics are always of the highest quality, attained by very few manufacturers. Mount: High quality, wooden, alt-azimuthal dobsonian mount • Mirrors are typically 1.3-m F/2.3 mirrors for the wide field F/4 telescopes. Accuracy of the parabolic surface: Strehl > 0.95 All mirrors are finished and documented by Carl Zambuto and coated and center-spotted in-house at the ZOC facility. Standard full-thickness parabolic Newtonian primary mirrors 8 through 16" in diameter and the NEW! • These mirrors have a surface departure from the best fit sphere of 60 waves. The design is made of high-quality multilayered plywood from the Austrian company JAF. Focal length: F=1200 mm A meniscus mirror is a concave mirror with a convex backside; a telescope mirror featuring a constant thickness. Focal ratio: f/4.2 Focal length: F=1600 mm The Strehl ratio of the parabolic surface is above 95%. Accuracy of the parabolic surface: Strehl > 0.95 Pre-order your custom meniscus mirror or custom slumped blank now! Premium Telescope Optics "I finally got a chance to take the 15” f/4.5 to a semi-dark site, Clarence Fahnestock Park. Copyright 2006 - 2020       AstroReflect LTD. Our new telescope "Gemini" combines the advantages of the classic Dobsonian mount, but with an improved, lightweight and easy to assemble truss design. Each mirror is custom made to order which includes custom focal lengths of any specification within range. Secondary mirror: D=82 mm Newtonian Telescope Mirrors . At the end a final test is made with an interferometer and the mirror is certified. Our mirrors are made with extreme precision and with exceptional quality. This results in a mirror that cools fast and evenly across its entire area. Interferometric test with a certificate: Yes The work ends when a Strehl ratio of 0.95 or more is achieved. Meniscus Mirrors will soon start the production of premium quality meniscus mirrors and custom slumped blanks for newtonian telescopes! Interferometric test with a certificate: Yes Accuracy of the parabolic surface: Strehl > 0.95 The results give an indication of product quality at multiple points over the entire surface, not just one. Disassembled: heaviest part - 9kg, largest part: 46x46x32cm, Aperture: D=200 mm (8") The telescopes we make are for the real connoisseurs.
