Lens materials are classified by their refractive index, as follows: Normal index: 1.48 ≤ n d < 1.54; Mid-index: 1.54 ≤ n d < 1.60; High-index: 1.60 ≤ n d < 1.74; Very high index: 1.76 ≤ n d; This is a general classification. Often for marketing purposes, materials with n d values that are at or above 1.60 can be referred to as "high ...

The list of confiscated media should not be confused with the List of Media Harmful to Young People (also known colloquially as The Index), as indexed video games are not considered banned. However, indexed video games are subject to strict restrictions and may only be offered and sold to adults.
A high-refractive-index polymer (HRIP) is a polymer that has a refractive index greater than 1.50. [1] Such materials are required for anti-reflective coating and photonic devices such as light emitting diodes (LEDs) and image sensors. [1] [2] [3] The refractive index of a polymer is based on several factors which include polarizability, chain ...
Rainbow Friends. Rainbow Friends is an episodic horror game developed by Roy & Charcle [ 94] where players attempt to escape the titular group of monsters (namely, Blue, Green, Orange, Purple, Yellow and Cyan) by collecting items. [ 82] Players can hide in a box to avoid detection. [ 95]
Roblox occasionally hosts real-life and virtual events. They have in the past hosted events such as BloxCon, which was a convention for ordinary players on the platform. [36] Roblox operates annual Easter egg hunts [43] and also hosts an annual event called the "Bloxy Awards", an awards ceremony that also functions as a fundraiser. The 2020 ...
Gradient-index ( GRIN) optics is the branch of optics covering optical effects produced by a gradient of the refractive index of a material. Such gradual variation can be used to produce lenses with flat surfaces, or lenses that do not have the aberrations typical of traditional spherical lenses. Gradient-index lenses may have a refraction ...
Standard refractive index measurements are taken at the "yellow doublet" sodium D line, with a wavelength (λ) of 589 nanometers. There are also weaker dependencies on temperature , pressure / stress , etc., as well on precise material compositions (presence of dopants , etc.); for many materials and typical conditions, however, these ...
