S-PHM52Q Optical Glass
Description
S-PHM52Q
Improved processability and chemical durability
S-PHM52Q is an optical glass with the same refractive index as S-PHM52 and nearly the same abbe number. Optical materials in the PHM region are generally characterized by a large, negative dn/dT value. However the dn/dT value of S-PHM52Q is actually close to 0, enabling an optical design that suppresses the effects of temperature drift. In addition, while S-PHM52 has the lowest dispersion and largest number of relative partial dispersion deviation of ⊿θg, F in nd ≒ 1.62, it is also soft, relatively fragile, and easily scratched. S-PHM52Q has improved workability and chemical durability while maintaining the same basic optical properties.
