Near-infrared radiation range objectives for bright-field observation (with cover-glass thickness compensation) LCD Plan Apo NIR / LCD Plan Apo NIR HR
VMU
FS70 WIDE VMU
Features
> Bright-field observation/near-infrared observation/laser machining > Wavelength compensation range 480 nm to 1800 nm > Infinity corrected > Long working distance > Plan-apochromat > Design enables observation through a 3.5 mm or 1.1 mm cover glass (material: BK7). Note: Mitutoyo is ready to design and manufacture a specific sheet of glass according to a specified glass thickness, material or refractive index, please contact your local Mitutoyo sales office. > High-resolving power type (LCD Plan Apo NIR HR)
