Description

Technical Field

[0001] This utility model relates to the field of optical processing equipment technology, specifically to an elastic clamping device for rapid positioning of optical components. Background Technology

[0002] Optical components are devices designed and manufactured using optical principles to control, manipulate, or detect light waves. They are core components of optical systems (such as microscopes, cameras, lasers, and fiber optic communication systems). They can alter the direction of light propagation, intensity, phase, polarization state, or spectral distribution.

[0003] The following is an introduction to the classification and common types of optical components:

[0004] I. Main Classifications (by Function)

[0005] Refractive element: It changes the path of light by utilizing the law of refraction.

[0006] lens:

[0007] A convex lens (converging lens) converges parallel light rays to a single point (focal point).

[0008] Concave lens (diverging lens): causes parallel light rays to diverge, and their backward extensions intersect at a point (virtual focal point).

[0009] Applications: Imaging (cameras, telescopes, microscopes, eyeglasses), focusing, collimation, beam shaping.

[0010] Prism:

[0011] Dispersive prism: It uses the different refractive indices of different wavelengths of light to decompose white light into a spectrum (such as a Newtonian prism).

[0012] Reflecting prisms: These utilize total internal reflection to change the direction of light and / or the orientation of the image (such as right-angle prisms, pentagonal prisms, and roof prisms), and are commonly used in periscopes, binocular telescopes, etc.

[0013] Beam splitter: A beam of light is split into two or more beams (such as a cubic beam splitter).

[0014] Polarizing prisms: used to generate or detect polarized light (e.g., Nicol prisms, Wollaston prisms).

[0015] Applications: spectral analysis, beam steering, image rotation, polarization control, beam splitting.

[0016] Reflective element: It changes the path of light by utilizing the law of reflection.

[0017] Plane mirror: The simplest reflecting element, it changes the direction of light without changing the characteristics of the light beam (ideally).

[0018] Spherical mirror:

[0019] Concave mirror (converging mirror): It converges parallel light rays to a focal point.

[0020] Convex mirror (diverging mirror): causes parallel light rays to diverge.

[0021] Aspherical mirrors: Surfaces that are not spherical (such as parabolic, hyperboloid, or ellipsoidal surfaces) are used to eliminate aberrations such as spherical aberration, improve image quality, or achieve special beam shaping (such as in large telescopes and laser focusing systems).

[0022] The production process of optical components involves surface polishing and grinding. Traditional optical component processing often uses metal chucks or vacuum suction cups to fix the workpiece, which has the following problems:

[0023] 1. Rigid contact with metal chucks can easily scratch the edges of workpieces (especially brittle materials such as calcium fluoride crystals).

[0024] 2. Vacuum chucks require a high degree of flatness on the bottom surface of the workpiece; thin components are prone to deformation during adsorption.

[0025] 3. Changing to workpieces of different sizes requires complete disassembly of the fixture, which takes a long time.

[0026] This solution provides a quick clamping device that can adapt to different sizes and avoid damage to the workpiece surface, solving the problems of low clamping efficiency and easy damage to workpieces in existing technologies.

[0027] Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Utility Model Content
