What is ISO 19056‑2 -Illumination properties related to the colour in bright field microscopy about?
ISO 19056‑2 is the second part of a series of international standards on microscopes.
ISO 19056‑2 discusses the colour properties of bright field microscopy.
ISO 19056‑2 specifies measurands and measurement procedures of colour properties for bright field microscopy with transmitted light illumination. These measurements are defined in image planes or intermediate image planes.
ISO 19056‑2 also specifies how the information is provided to the user.
Who is ISO 19056‑2-Illumination properties related to the colour in bright field microscopy for?
ISO 19056‑2-Illumination properties related to the colour in bright field microscopy is useful for:
- Microscope manufacturers
- Microscope testing engineers
- Microbiology practitioners
Why should you use ISO 19056‑2-Illumination properties related to the colour in bright field microscopy?
The colour temperature is an index to express the colour by a single parameter when the chromaticity of the light source is on the black body locus. However, actual light sources do not completely match with the black body radiation. Therefore, the correlated colour temperature, i.e., the colour temperature of the nearest colour on the black body locus is used.
ISO 19056‑2 specifies methods for calculating the correlated colour temperature by using the CIE 1960 UCS chromaticity and the chromaticity coordinates.
ISO 19056‑2 provides the settings of the microscope to eliminate their influence on the measurement results. ISO 19056‑2 also specifies information on the measurement environment, the lights sources and the stability of measurements.
As a user of ISO 19056‑2, you can be ensured of the colour properties and measurement procedures of colour properties of bright field microscopy. With obedience and compliance to ISO 19056‑2, you can efficiently calculate the correlated colour temperature by using the CIE 1960 UCS chromaticity and the chromaticity coordinates. ISO 19056‑2 provides you with comprehensive information useful throughout the process of measurement of colour in bright field microscopy.
