Chemical indicator element systems for aquatic environment water parameter testing
First Claim
1. A chemical indicator element for use in an aquatic environment water parameter testing system having a light source capable of generating an excitation energy and a light sensor for detecting light, the chemical indicator element comprising:
- a chemical indicator responsive to a first excitation energy to generate a first emitted energy in response to the first excitation energy;
a backing material that absorbs one or more wavelengths of light of the first excitation energy; and
a thin film material positioned proximate the chemical indicator between the chemical indicator and the backing material, the thin film material being configured to;
absorb and/or allow transmission of one or more wavelengths of light of the first excitation energy, andreflect one or more wavelengths of light of the first emitted energy.

Abstract
A chemical indicator element for use in an aquatic environment water parameter testing system. The chemical indicator element includes a chemical indicator and a thin film material having particular optical characteristics tied to the light from a light source, such as a light source of an optical reader element of a water parameter testing system. The chemical indicator element may also include at least one of a backing material that absorbs one or more wavelengths of the light of the light source and a holder including a material that absorbs one or more wavelengths of the light of the light source.
