BK7 lens array MLA150-5C

microscopicanti-reflective

Features 10 mm x 10 mm High-Quality Microlens Array Available Unmounted or in a Ø1" Mount Two Wavelength Ranges Available: 400 - 900 nm with an AR Coating 300 - 1100 nm with a Chrome Mask Fused Silica Substrate Square Grid Arrangement of Microlenses Arrays with 150 µm or 300 µm Lenset Pitches Available Near Diffraction-Limited Spot Size High Spot-to-Background Contrast Use for Custom-Built Shack-Hartmann Wavefront Sensors These Fused Silica Microlens Arrays are available mounted or unmounted (click here to see an enlarged photo). Fused silica offers excellent transmission characteristics from the UV to the IR. The microlenses have a plano-convex shape and are arranged in a square grid with a lens pitch of 150 µm or 300 µm. The arrays with a pitch of 150 µm have round lenslets. The arrays with a pitch of 300 µm have square lensets, allowing for a fill factor of 100%. The MLA150-5C lens array and its mounted counterpart have a chrome mask that blocks light from being transmitted through the spaces between microlenses, thereby increasing the constrast. The unmounted MLA150-7AR and MLA300-14AR lens arrays and their mounted versions have a broadband AR coating on both sides to reduce the surface reflections in the 400 - 900 nm spectral region to below 1%.
