A8V series inclined shaft plunger hydraulic pump adopts spherical flow and arc surface adjustment. Taking A8V80 as an example, the structure of oil distribution plate is shown in Figure 1. The processing of this type of parts is mainly focused on the key characteristics of the spherical surface and the curved surface. The short-arc grinding grinding jig is now introduced as follows (the size shown in Figure 1 is the final size).

Zinc Sulfide Lens

Multi-spectral grade of zinc sulfide has low absorption and scatter properties over its broad transmission range of 0.4 - 12μm. Zinc Sulfide Multispectral is a chemically vapor deposited material which is commonly used in thermal imaging. With its excellent transmission properties in the visible and infrared, Zinc Sulfide Multispectral is the material of choice for systems that have both visible and mid-wave or long-wave infrared sensors. It is slightly harder and more chemically resistant than zinc selenide.

We consistently offer various high quality optical components according to the customer's requirements use other infrared materials. Such as prisms,Spherical Lens, aspherial lens,Ball lens,Optical Windows,Achromatic Lens,cylinder lens etc.
