NDIR detector device for detecting gases having an infrared absorption spectrum

A device, comprising:

• a support having a bearing surface;
• a spacer body coupled to the bearing surface, the spacer body including:
• a first surface coupled to the bearing surface of the support;
• a second surface opposite to the first surface, the second surface being spaced apart from the baring surface and facing away from the bearing surface of the support;
• an emission opening extending into the second surface of the spacer body to the bearing surface of the support;
• a reception opening spaced apart from the emission opening and extending into the second surface of the spacer body to the bearing surface of the support;
• and
• a channel extending into the second surface of the support body to the bearing surface of the support, the channel being positioned between the emission opening and the reception opening and exposing an area of the bearing surface of the support between the emission opening and the reception opening.

A device, comprising:

• a support body including a bearing surface;
• a light-emitting element on the bearing surface of the support body, the light emitting element including a light emitting surface spaced apart from the bearing surface of the support body and facing away from the bearing surface of the support body;
• a light-receiving element on the bearing surface of the support body and spaced apart from the light-emitting element, the light-receiving element including light-receiving surface spaced apart from the bearing surface of the support body and facing away from the bearing surface of the support body;
• and
• a spacer body on the light-emitting element and the light-receiving element, the spacer body partially covering the light-emitting surface of the light-emitting element and the light-receiving surface of the light-receiving element, the spacer body including:
• a surface spaced apart from the bearing surface of the support and facing away from the bearing surface of the support;
• an emission opening extending into the surface of the spaced body to the light-emitting surface and exposing the light-emitting surface;
• and
• a reception opening extending into the surface of the spacer body to the light-receiving surface and exposing the light-receiving surface.
