Product Description

Infinity-corrected plan semi-apochromatic design
Designed for use with 180 mm tube lenses
Thread specification: W20.32 mm×0.706 mm (RMS)
Dry objectives and oil immersion objectives available

LBTEK offers Olympus plan semi-apochromat objectives. These lenses feature standard RMS threads, an infinity-corrected plan semi-apochromatic design, and are designed for use with tube lenses with a focal length of 180 mm. Plan semi apochromat objectives, typically made of fluorite (CaF2), offer achromatic performance intermediate between plan achromatic and plan apochromatic objectives. LBTEK offers Olympus plan semi-apochromat dry objectives with magnifications of 4X, 10X, 20X, 40X, 50X, 60X, and 100X, as well as oil immersion objectives with magnifications of 60X and 100X.

Olympus Plan Semi-Apochromat Dry Objectives

Infinity-corrected plan semi-apochromatic design
Designed for use with 180 mm focal length tube lenses
Thread specification: W20.32 mm × 0.706 mm (RMS)

LBTEK offers Olympus 4X, 10X, 20X, 40X, and 60X (with correction collar) Plan Semi-Apochromat Dry Objectives. Each objective features standard RMS threading and can be mounted to SM1 internal threaded mounts using LBTEK's SM1-RMSA thread adapter. All five objectives are well-suited for brightfield microscopy, with the 10X, 20X, 40X, and 60X magnification models also being highly compatible with DIC (Differential Interference Contrast) microscopy. Please refer to the product specifications list below for detailed parameters.
