Ohara’s WMS-15 glass-ceramic substrates will enable manufacturers to produce leading edge DWDM and Gain-Flattening Filters. Our WMS substrates will facilitate the production of filters with extremely low thermal wavelength drift and low insertion loss values. WMS-15 has improved internal transmittance and exceptionally low surface roughness values.
* CTE=114 x10-7/K(-30~70ºC): Standard material, Please consult us with higher CTE requirements.
* All properties are measured at room temperature except for CTE and dn/dt.
* Refractive Index and dn/dt is calculated value.
* Properties subject to change along development.
