Review of glass portfolio

 

To whom it may concern,

According to the latest review of our glass portfolio, we will do a reclassification of following glass-types, effective from May, 1St 2019:

Change to “special order”:

S-LAH79, S-NPH53, L-LAH86 und S-TIM1.

S-LAH60MQ

S-LAH60MQ is an optical glass with high refractive indices which has the smallest dn/dT among current LAH glasses.
Cars are used in environments where the temperature change is large from below zero (cold district) to more than 50 °C  (inside car in summer). The large differences of the temperature may cause refractive index fluctuations. Zoom lens could adjust the refractive index fluctuations. But fixed-focus lens is common in the field of Automotive cameras and it's impossible for us to adjust the refractive index fluctuations with fixed-focus lens.
Whereas many LAH glasses have large...

S-NBH58

Though S-NBH58 has high refractive indices with high dispersion, the partial dispersion ratio θg,F is low. That's why S-NBH58 could be effective for correcting chromatic aberration by combining it with anomalous dispersion glasses having both low refractive indices and low dispersion. We are pleased to introduce S-NBH58 which could be effective for higher performance of customer's products and could be used for various applications such as the lenses of Interchangeable lens cameras, Projectors and so on.

S-NPH7

S-NPH7 is an optical glass which has the smallest dn/dT in the region of NPH, high refractive indices and high dispersion. In the optical system of the Automotive camera lens, it's common that the focal length is fixed. Cars are used in environments where the temperature change is large from below zero (in cold district) to 50 ° C or above (inside car in summer). When we make the design of optical system, considering refractive index fluctuations due to temperature change should be needed. Generally speaking, NPH glasses have positive dn/dT and the value of dn/dT is large at the positive side....
