Problems solved by technology

Even though this is not a problem in some optical systems, in coated systems a change in the index of refraction can cause a change in transmission
These changes can have a large impact when considering the many parametric detection systems making very fine-grained measurements

Embodiment Construction

[0091] Example glass substrates and example filters were fabricated and some characteristics were measured. The tested glass compositions can be found in Table 1 below.

[0092] composition example

[0093] Table 1 below shows exemplary glass compositions (in cat.-%) used as the composition of the substrate glass of the present invention. The glasses shown in Table 1 contain only oxides as anionic components, ie the glasses are oxides.

[0095]

[0096]

[0097] The above composition is the final composition of the measured glass. Those skilled in the art know how to obtain these glasses by melting the necessary raw materials.

[0098] Manufacture of glass substrates

[0099] Glasses were made using suitable raw materials to obtain the final compositions shown in Table 1. The raw materials are melted in the melting crucible. After melting, the glass is formed into a thin glass product with a thickness of about 0.3 mm.

Description

technical field [0001] The invention relates to a parameter detection system, an infrared band-pass filter, a glass substrate for the infrared band-pass filter, and a parameter detection method. The system can be used, for example, to detect individual parameters such as iris recognition, 3D scanning, touch sensors, biometrics, interactive displays, gaming and gesture control. [0002] For the purposes of the present invention, a "parameter detection system" is generally an electronic system capable of measuring at least one parameter of at least one individual or object. The measured parameter may be selected from any parameter measurable using optical methods. "Detection" includes identification and / or quantification of individual parameters. Background technique [0003] Gesture control devices, iris scanners and other related parameter detection devices are prior art per se. These devices generally have an infrared light source (illumination unit) for illuminating the...
