SCHOTT S8851 multibandpass filter glass for spectral and display contrast evaluation (tri-notch selection). 1.6 mm requested finished thickness; BBAR / AR — One Surface. Cut size, availability and fabrication confirmed by quotation.
Tri-notch is the display-selection term used here for SCHOTT multibandpass materials. The graph uses published S8851 data, not an idealized RGB curve. Multiple passbands do not guarantee a match to every LCD: compare the material with the actual RGB emission, ambient spectrum and viewing requirements.
The dashed curve is SCHOTT internal transmittance at 2 mm. Colored curves estimate 0.7, 1.1, 1.6, 2 and 3 mm using Ti(d) = Ti(dref)d/dref. Source: SCHOTT S8851 datasheet, 05.12.2023, sampled every 10 nm. Values between samples are connected for readability; narrow spectral structure may require finer data.
Calculated values assume homogeneous material and normal incidence. Internal transmittance excludes surface reflection and BBAR/AR effects; these curves are not finished coated-component transmission. Below-limit source samples, where present, are plotted as upper bounds. Graph thicknesses do not establish stock or fabrication availability.
1.6 mm is a requested custom finished thickness. Review blank size, cutting or slicing, grinding, polishing, flatness, edges and spectral tolerance for the project.
One optical surface specified for BBAR / AR treatment; identify the coated face and coating band. Coating performance is confirmed separately.
