Products
Landmark Engineering offers a wide range of optical parts based on customer’s requirements, ensuring a complete service. With several years of manufacturing experience, the company welcomes all inquiries and strives to meet or exceed expectations.
Spherical lens
We have specialized in lens manufacturing from beginning and offer a wide range of lenses, including single, double, miniscule, and cylindrical types, with diameters up to 250 mm. These lenses have high wavefront accuracy of λ/10 PV @633 nm, surface quality of 10/5, and general surface roughness of less than 0.05λ RMS.
Aspherical lens
Our products have a maximum diameter of 250 mm high wavefront accuracy of up to λ/10 PV @633 nm and surface quality of 10/5 with a general surface roughness below 0.05λ RMS. These lenses are ideal for applications requiring low f-numbers and high light transmission.
Prisms and filters
We produce parts up to 150 mm in size, considering all types and configurations, including single and adhesive lenses. Our products have high precision, with angle accuracy better than 5 seconds, surface accuracy of λ/10 PV @633 nm, surface quality of 10/5 and general surface roughness of less than 0.05λ RMS.
Flat Mirrors
We offers high-quality referenced and coated flat mirrors, along with precision alignment equipment for optical and engineering applications. These mirrors are used for reference, beam folding, positioning and system downsizing. these products have a maximum diameter of 300 mm and non-circular shapes. They have high surface accuracy of λ/20 PV @ 633 nm, surface quality of 10/5, and general surface roughness of less than 0.05λ RMS.
