Sapphire Step Window

Sapphire step windows, is also called T-Windows are excellent for use in viewports, pressure, and vacuum situations. Sapphire glass step windows also make great viewports for deep ocean vehicles. Sapphire pressure windows stand up well to the abusive salt water and debris while being less thick than other traditional glass counterparts.

What is a sapphire lens?

Sapphire is extremely strong and scratch resistant – making it the top choice for a fine timepiece. While sapphire is the more expensive of the three crystal choices, it has its advantages due to the scratch and shatter resistance.

High Temperature Quartz Tube

VY Optoelectronics Co.,Ltd. carries a wide range of sizes of quartz high temperature glass tube to cover applications such as general lighting, laser flash lamps, digital projection, semiconductor (lithography/cleaning), UV disinfection, and UV curing. Materials are available as standard stock items or custom fabrication with precision accuracy.

What are cylindrical lenses?

A cylindrical lens is a lens which focuses light into a line instead of a point, as a spherical lens would. The curved face or faces of a cylindrical lens are sections of a cylinder, and focus the image passing through it into a line parallel to the intersection of the surface of the lens and a plane tangent to it. The lens compresses the image in the direction perpendicular to this line, and leaves it unaltered in the direction parallel to it (in the tangent plane).

Happy Lantern Festival! #festival #LanternFestival

Lantern Festival, also called Yuan Xiao Festival, holiday celebrated in China and other Asian countries that honours deceased ancestors on the 15th day of the first month (Yuan) of the lunar calendar.

How does Band Pass Filter Work?

Bandpass filters are widely used in wireless transmitters and receivers. The main function of such a filter in a transmitter is to limit the bandwidth of the output signal to the band allocated for the transmission. This prevents the transmitter from interfering with other stations. In a receiver, a band pass filter allows signals within a selected range of frequencies to be heard or decoded, while preventing signals at unwanted frequencies from getting through.

what is a pentaprism what job does it do in the camera?

Penta prism is a five-sided reflecting prism used to deviate a beam of light by a constant 90°, even if the entry beam is not at 90° to the prism. The beam reflects inside the prism twice, allowing the transmission of an image through a right angle without inverting it (that is, without changing the image's handedness) as an ordinary right-angle prism or mirror would.

What are cylinder lenses?

Cylinder lenses are a type of lens that have differing radii in the X and Y axes, causing the lens to have a cylindrical or semi-cylindrical shape, and image magnification in only a single axis. Cylinder lenses are commonly used as laser line generators, or to adjust image height size or correct for astigmatism in imaging systems.

How does a Fresnel lens work?

A Fresnel lens is an optical component used as an alternative to a conventional lens due to it being lighter and more cost-effective. Since the refractive power of a lens is in the optical interfaces - the lens surfaces - in a Fresnel lens the optical material is removed as much as possible while maintaining the surface curvature
