Vật kính PL FLUOTAR (PL-FL)

Model:
Tình trạng: Liên hệ

PL Fluotars are powerful universal objectives with outstanding chromatic correction for at least three wavelengths which makes them suitable for fluorescence imaging.

Field planarity (PL) is computed for a 25 mm field of view. They are made of special glass to enable maximum transmission. This makes them powerful photon collectors in fluorescence microscopy.

Leica’s Fluotar portfolio features various application-optimized correction collars (CORR) to compensate for external influences such as temperature, coverslip thickness and immersion media.

Leica Semi-Apochromat

Leica semi-apochromats are objectives for applications in the visual spectral range with higher specifications, offering field flatness up to 25 mm.

The absolute values of the focus differences for the red wavelength and the blue wavelength to greenwavelength (3 colors) are ≤ 2.5x depth of field of the objective.

Objective Classes

Objectives are categorized into performance classes on the basis of their transmission, chromatic correction, planarity, and others. From the point of view of the International Organization of Standardization (ISO), there are three groups of objective classes differing in quality of chromatic correction.

Objective Class	Field Flatness	Absolute Value(s) of Focus	Application
Achromats	up to 23 mm	between red and blue wavelength (2 colors) is ≤ 2x depth of field	for standard applications in the visual spectral range
Semi-Apochromats	up to 25 mm	for red wavelength and blue to green wavelength (3 colors) are ≤ 2.5x depth of field	for applications in the visual spectral range with higher specifications
Apochromats	up to 25 mm	for red wavelength and blue to green wavelength (3 colors) are ≤ 1x depth of field	for applications with highest specifications in the visual range and beyond

Depth of field:

Leica Microsystems has aligned all three performance classes of its range of objectives to the needs of its customers and the specific requirements of a wide variety of applications – while offering a convincing price-performance ratio.
