The glass filter is mounted in an alloy holder with dimensions equivalent to a standard cuvette. This wavelength standard is offered in two (2) product versions: CRM 150 and CA2M 752.
STRANASKA® CRM 150
- glass equivalent to NIST SRM 2013
- certified for absorption bands in the spectral range ~ 340 nm to 880 nm
- one (1) spectral bandwidth (1 nm)
- certified with routine scientific metrological rigor and traceability that is consistent with prevailing standard industry practices
- routine uncertainty budget
STRANASKA® CA2M 752
- enhanced version of CRM 150
- certified for absorption bands in the spectral range ~ 340 nm to 880 nm
- one (1) spectral bandwidth (1 nm)
