Microscope Objectives

Optosigma Microscope Objectives are precision optical objectives for scientific and industrial microscopy, compatible with standard RMS thread and infinity optical tube length systems.

Plan apochromat objectives:
– Highest correction class: apochromatic chromatic correction for three wavelengths; flat field across full field of view
– NA range: 0.08 (2x) to 1.45 (100x oil); covers dry, water, and oil immersion
– Transmission: UV-optimized versions for 340 nm excitation (DAPI, Hoechst); standard versions for 400-700 nm
– Coverslip correction: corrected for 0.17 mm coverslip (standard No. 1.5); correction collar versions for variable thickness

Long working distance objectives:
– LWD and ULWD versions: working distance 3 mm to 30 mm at 20x to 50x
– For in-vitro samples, incubation chambers, and thick specimens
– Dry objectives; no immersion required

Laser-compatible objectives:
– Anti-reflection coated for laser wavelengths: 405 nm, 488 nm, 532 nm, 635 nm, 785 nm
– Low autofluorescence glass for fluorescence microscopy
– Infinity corrected for use with tube lens in scanning systems

Specialty objectives:
– Near-IR objectives: optimized for 750-1100 nm; used in two-photon and NIR fluorescence microscopy
– UV objectives: fused silica construction; transmission to 250 nm
