Sanfeng Near-Uv Color Correction M Plan NUV Uv Objective Lens 355nm To 620nm Spot

SPECIFICATION:

Mag.: magnification

N. A.: numerical aperture

W. D.: working distance

f: Focal length

R: Resolution

D. F.: depth of field

Field of view 1: the field of view when a 024mm eyepiece is used

Field of view 2: the field of view when a 1 / 2 "CCD camera is used

Note:

These objective lenses are designed to image the workpiece within the depth of field (when the wavelength changes between visible light (wavelength = 620nm) and near ultraviolet light (wavelength = 355nm)). Therefore, m plan NUV series is suitable for laser repair using high-frequency laser beam.

Basic types of objective lenses

The microscopic objective lens is the most critical part of the optical microscope, and it is also the most difficult part to design and assemble. The objective lens is assembled by a series of lenses. The imaging quality of the objective lens directly determines the performance of the microscope system. When selecting an appropriate objective lens, in addition to the above-mentioned technical indexes such as magnification and numerical aperture, it is also very important to understand the correct aberration correction.

According to different aberration correction conditions, micro objective can be divided into achromatic objective, compound achromatic objective, flat field achromatic objective, flat field compound achromatic objective and so on.
