2. High-refractive-index polymer - Wikipedia

   en.wikipedia.org/wiki/High-refractive-index_polymer

   A typical polymer has a refractive index of 1.30–1.70, but a higher refractive index is often required for specific applications. The refractive index is related to the molar refractivity, structure and weight of the monomer. In general, high molar refractivity and low molar volumes increase the refractive index of the polymer.

   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-index". Likewise, Trivex and other borderline normal / mid-index materials may be referred to as mid-index.

4. Abbe number - Wikipedia

   en.wikipedia.org/wiki/Abbe_number

   In optics and lens design, the Abbe number, also known as the Vd-number or constringence of a transparent material, is an approximate measure of the material's dispersion (change of refractive index versus wavelength), with high values of Vd indicating low dispersion.

5. Optical properties of water and ice - Wikipedia

   en.wikipedia.org/wiki/Optical_properties_of...

   The refractive index of water at 20 °C for visible light is 1.33. [1] The refractive index of normal ice is 1.31 (from List of refractive indices). In general, an index of refraction is a complex number with real and imaginary parts, where the latter indicates the strength of absorption loss at a particular wavelength. In the visible part of ...

6. Image sensor format - Wikipedia

   en.wikipedia.org/wiki/Image_sensor_format

   The development of the 'Tessar' lens is discussed by Nasse, [11] and shows its transformation from an f /6.3 lens for plate cameras using the original three-group configuration through to an f /2.8 5.2 mm four-element optic with eight extremely aspheric surfaces, economically manufacturable because of its small size. Its performance is 'better ...
