Near-IR Long Working Distance Plan Achromat - LMPLN-IR/LCPLN-IR

 OLYMPUS Objective Lenses

Microscope Objective

SPECIFICATION:

Our LMPLN-IR and LCPLN-IR long working distance Plan Achromat lenses, are specifically designed for optimal transmission in the near infrared (700-1300nm wavelengths).

Product description

Objective lenses exclusive for the near-infrared microscopy, for inspecting internal structures in silicon wafers

The LCPLN-IR lenses have correction collars that adjust for varying thicknesses of silicon or glass substrates
