LBTEK-Your Trusted Partner For Optoelectronic Experiments!

Product Description

Semi-apochromat and apochromat options available
Dry objectives, water immersion objectives, and oil immersion objectives available
Designed for tube lenses with a focal length of 200 mm

LBTEK offers a wide variety of Nikon infinity-corrected microscope objectives covering wavelengths from the ultraviolet to the near-infrared, suitable for brightfield, darkfield, DIC, fluorescence, polarizing, multiphoton, and phase-contrast microscopy. LBTEK's Nikon objectives are categorized by their achromat performance: plan semi-apochromat objectives (also known as plan fluorite or plan fluorite objectives) and apochromat objectives. Apochromat objectives offer higher image quality than semi-apochromat objectives. They are also categorized by the immersion fluid used for imaging: dry, oil, and water immersion objectives. The NAPO25XCW-MP and NAPO25XCW-MP1300 objectives are optimized for deep tissue imaging using multiphoton confocal microscopy and are ideal for multiphoton imaging. The NPLNFL10XDLL and NPLNFL10XDLL objectives are designed for positive phase contrast imaging and are an excellent choice for phase-contrast microscopy. Objectives can be adapted to 1" optics mounts using the LBTEK adapters SM1-M25A or SM1-M32A.

Nikon Plan Semi-Apochromat Phase Contrast Objectives, DLL (Dark Low Low)

Infinity-corrected plan semi-apochromatic design
Thread type: M25 mm×0.75 mm
Phase type: DLL

LBTEK offers Nikon 10X and 20X plan semi-apochromat phase contrast objectives with excellent transmittance from the ultraviolet to the visible wavelength range. To achieve optimal phase contrast, these objectives require a corresponding annular diaphragm. The choice of annular diaphragm depends on the microscope model. Please contact LBTEK technical support for selection.

LBTEK's phase contrast objectives are positive phase contrast objectives. Light passing through the object destructively interferes at the image plane, creating a dark image against a bright background for high contrast. The principle of positive phase contrast objectives is described in the technical description. Specific parameters are available in the product specification list.

The LBTEK thread adapter SM1-M25A allows these objectives to be mounted on mounts with internal SM1 threads.
