HO-PVL25-02 25mm Dia. N-BK7 Plano-Concave Lens; EFL=-50mm Uncoated
This is a Plano-Concave Lens, a type of spherical lens, offered by Holmarc Opto-Mechatronics. The lens has a base shape of a circle and a diameter of 25mm. The center thickness of the lens is 2.5mm. The effective focal length (EFL) of this lens is -50mm, indicating that it is a diverging lens, causing parallel rays to spread out.
The lens is made of N-BK7, a type of glass commonly used in optical systems due to its excellent optical properties. The refractive index of N-BK7 varies with wavelength, and in this case, it is specified for a wavelength of 587.6nm. The inner and outer radii of the lens are both zero, indicating that the lens is plano-concave, meaning one side is flat, and the other side is curved inwards.
The lens does not come with any coating, as indicated in the item data. Coatings are often applied to lenses to enhance their optical properties, such as reducing reflection or increasing transmission. However, this lens is uncoated, which may be suitable for certain applications where such enhancements are not required.
The lens is currently in stock and can be purchased directly from the vendor's website. More information about this lens and other similar products can be found on the vendor's website, which is provided in the item data.
