Opto Sigma

• Highly corrected and optimized for minimum spot size
• For use with most low power lasers with collimated output beams
• Standard microscope objective threads for easy mounting
• Fully color corrected for use throughout the visible

Microscope objectives are ideal for use as focusing lenses for low power lasers such as HeNe, HeCd, and N2. We offer a selection of precision achromatic objectives covering a range of numerical apertures. They are housed in conventional microscope barrels and fitted with a standard RMS microscope thread. The lenses are Anti-Reflection coated.
