Manufacturing Process
The engineers at Elyonoptics calculate the required machining allowances based on the dimensions and materials of the parts provided in the customer’s drawings, and prepare machining instructions (including the tooth wear degree of the material, refractive index, Mohs hardness; calculating the equipment pressure, machining time, swing angle, rotational speed, swing speed during the process, as well as the diameter, thickness, curvature, number of fringes, surface figure, and surface finish inspection criteria to be controlled in each machining step), which are then distributed to each production department. Based on the established machining steps, they design the required cast iron molds, aluminum molds, copper molds, POM fixtures, and coating umbrellas (specific products may use aluminum fixtures for clamping, custom-curvature pressure heads, coating umbrellas, etc.).
The CNC technicians at Elyonoptics process the required cast iron, aluminum, copper, POM fixtures, coating umbrellas, and other jigs based on the fixture drawings designed by the engineers.
(For batch products, multi-piece processing jigs are specifically designed according to the product’s aperture and curvature.)
The technicians at Elyon Optics perform precision height correction on freshly processed polishing molds
grinding the diamond pellet until it matches the reference template’s dial indicator readings.
The material department of elyonoptics will locate the corresponding material for processing based on the rough blank instruction manual drawn by the engineers, meeting the dimensional and material requirements specified in the drawings (elyonoptics can provide the corresponding material certification as per the drawing requirements!!

The milling department of Elyonoptics performs spherical/plane milling according to the work instructions drawn up by engineers. Based on the angle, rotational speed, and correction time specified in the instructions, fine adjustments are made to meet the required curvature, dimensions, and eccentricity requirements. After achieving the desired parameters, the angle, rotational speed, and correction time are precisely recorded to enhance efficiency in subsequent processing.
The grinding department of Elyonoptics performs spherical/plane grinding according to the work instructions drawn up by engineers, processing based on the specified swing angle, rotation speed, swing speed, pressure, and cutting fluid concentration provided in the instructions. After fine-tuning to achieve the required parameters such as f-number, dimensions, eccentricity, and surface finish, precise records are made to ensure both quality and efficiency in subsequent repeat orders.
The polishing department of Elyonoptics performs spherical/planar polishing according to the work instructions drafted by engineers. Processing is carried out based on the specified parameters in the work instructions, such as angle, rotation speed, pressure, oscillation speed, polishing fluid concentration, and whether acid addition is required. After fine-tuning to achieve the required indicators—including aperture, dimensions, surface figure, surface finish, and curvature—precise records are made to ensure both quality and higher efficiency for subsequent repeat orders.
Elyonoptics’ edging department selects grinding wheels of corresponding grit size based on the work instructions drawn by engineers, adjusts the fixtures, and processes the required eccentricity, outer diameter, platform, and chamfer according to the drawing specifications.
Elyonoptics’ ultrasonic cleaning department will clean the products and then spin-dry/oven-dry/air-dry them.
Elyonoptics’ inspection department conducts surface finish testing in a sealed, light-free cleanroom according to U.S. military standards. We are equipped with various wattage light sources (including fiber optic lights, cold light sources, yellow lamps, etc.), a 40x Leica microscope, 10x/20x ordinary magnifiers, visual microscopes, and other equipment for inspecting product surface finish.
Of course, for surface figure, curvature, eccentricity, transmittance, and center thickness, Elyon has corresponding inspection equipment: ZYGO interferometer, grating ruler (thousandth precision), full-European contact spherometer, Huayou eccentricity tester, contact thickness gauge (ten-thousandth precision), laser right-angle instrument, image measuring instrument, Agilent spectrometer, and other devices to ensure product quality for our customers. (We can provide inspection reports for surface figure, outer diameter, curvature, thickness, eccentricity, etc.!! Contact sales at sales@elyonoptics.com)
The coating department of elyonoptics can provide customers with various coating systems such as infrared anti-reflection coatings, diamond-like carbon (DLC) films, gold reflective coatings, and visible light anti-reflection coatings. (Test reports with witness samples are available!! Contact sales at sales@elyonoptics.com)
