PURPOSE:To obtain an objective lens with small flare by composing a lens system of a convergent front group which includes a meniscus lens component having a convex surface on an object side and a convergent rear group which includes a positive lens having a large-curvature surface on the ...
MICROSCOPE OBJECTIVE LENS WITH LOW POWER 优质文献 相似文献Microscope objective lens A microscope objective lens, sequentially from an object-side, comprises a first lens group constructed of a positive lens element, a second lens group constructed of a negative lens element, and a third lens group...
A larger lens with a lower magnification power. Wider field of view (how much you can see at once). It is shorter in length compared to higher-power lenses. Types of Objective Lenses Medium-power objective lens Magnification range and typical uses Magnification Range:20x to 40x Typical Uses:...
For instance, with a high magnification lens (100x) immersion oil is often used to obtain high resolving power. This is not the case with lower magnification objectives. Classification based on Aberration CorrectionEssentially, with regards to chromatic aberration correction, there are two main levels...

For example, this is the case for low-power single-mode laser diodes. When a lens with too low NA is used, the resulting collimated beam can be distorted (aberrated) or even truncated. There is a weak dependence of numerical aperture on the optical wavelength due to the wavelength ...
1. Screw the corresponding objective lens into the P76 objective scanner and tighten; 2. Screw the lens into the adapter and tighten; 3. Fix the installed piezo objective scanner and microscope connection section. 5.1 Installation and connection Note: During the installation process, please pay att...

In such a case, even in the upper limit position of the lens 1, a gap exists between the cover 12 and the lens 1, and even in the lower limit position, a gap exists between the cover 12 and the disk 13, therefore, each member is not brought into contact with each other. ...
An objective lens system for endoscopes comprising, in order from the object side, a first lens component having negative refractive power, a second lens component having positive refractive power and a third lens component having positive refractive power; wherein astigmatism is corrected favorably by...
