Optical Part Processing Method

-
As a Silicon Domes Manufacturer, let's introduce the processing methods of optical parts.
Optical processing can be divided into thermal processing and cold processing. Cold working is the sawing, rough grinding, fine grinding, polishing and centering of the parts. Today, we are going to share with you the related technologies and methods of centering and edging of optical parts processing.
The centering of the optical parts is determined by the fact that, for circular optical parts, the size of the side cylindrical surface meets the assembly requirements; for a spherical lens, the alignment of the two spheres (optical axis) and the axis of external symmetry (geometric axis) Deviation (center deviation c: cross center deviation and parallel center deviation).
Optical part processing lens centering method: optical centering method (surface reflection like centering method, projection image centering method, spherical center reflection image centering method), mechanical centering method and photoelectric centering method. Let's take a look at these methods of centering.

1. Lens surface reflection image centering method: This method is real image and has low precision.
2. Projection centering method: The essence is to observe the focus image of the centering lens with a microscope, and the precision is low.
3. Ball-center reflection image centering method: The essence is to use a self-collimating microscope to observe the number of beats of the cross-hair image on the reticle, with high precision.
Our company produces a variety of Optical Domes such as glass optical Domes, Fused Silica Domes and Custom Domes. Welcome everyone to come to consult and order.

  In the realm of optics,   cylindrical lenses ​   stand as unsung heroes, offering unparalleled versatility in various applications. From enhancing vision in eyewear to optimizing laser systems, these lenses play a pivotal role. In this comprehensive guide, we delve into the myriad uses of cylindrical lenses, shedding light on their significance across different industries. Cylindrical lenses characterized by their curved surface with different radii in the X and Y axes, serve a distinct purpose in manipulating light. Unlike traditional lenses, which correct  spherical aberrations , cylindrical lenses focus on addressing astigmatism and other optical anomalies. This unique design opens the door to a wide array of applications. Optical Clarity in Vision Correction One of the primary applications of cylindrical lenses lies in the realm of vision correction. Optometrists leverage these lenses to address astigmatism, a common refractive error that blurs vision due to irregularities in the
