Product Description

Didymium glass filter

NAC432666-F7 Didymium glass filter

Description	Didymium glass filter, solid filter, certified
Use	Assessment of wavelength accuracy in both the UV and visible range (329 nm to 875 nm) with a spectral bandwidth up to 2 nm
Material	Glass BG 36 of SCHOTT Glaswerke

The didymium glass filter 666-F7 made of SCHOTT glass BG 36 can be supplied to check the wavelength accuracy in both the UV and visible range.

This filter can additionally be used to check the photometric accuracy at wavelengths of 270 nm, 280 nm, 297 nm, 320 nm and 340 nm. Didymium glass shows a spectrum with a multitude of highly defined peaks. The heights and positions of these peaks are dependent on and will vary with the chosen slit width of the measuring instrument.

Precise Calibration and Wavelength Validation

This Didymium glass filter is specifically engineered for wavelength and photometric accuracy verification in UV-Vis spectrophotometers. With well-defined absorption peaks at 430 nm, 495 nm, and 577 nm, it enables users to confidently calibrate and periodically verify their instruments, ensuring reliable analytical results across a broad visible spectrum.

Robust Construction and Chemical Resistance

Fabricated from high-purity didymium glass, the filter provides excellent resistance to laboratory solvents and long-term stability. The polished edges and protective storage case safeguard the integrity of the filter, while its ambient temperature compatibility and durability support routine use in demanding laboratory settings.

User-Friendly and Reusable Design

The rectangular flat plate is easy to handle and integrate into standard spectrophotometer calibration processes. Its reusable nature allows cost-effective repeated usage under normal laboratory conditions, making it a sustainable solution for quality control and compliance in research and analytical laboratories.

FAQs of Didymium glass filter for UV Vis-Spectrophotometer:

Q: How is the Didymium glass filter used for spectrophotometer calibration?

A: The filter is placed in the sample holder of the UV-Vis spectrophotometer and measured at specific wavelengths. Its known transmittance peaks at 430 nm, 495 nm, and 577 nm are used to validate the instruments wavelength accuracy and photometric performance, following the procedure outlined in the manufacturers instructions.

Q: What benefits does the Didymium glass filter offer over other calibration materials?

A: This filter provides highly stable spectral absorption bands, superior chemical resistance, and reusability. Its reliable wavelength peaks are ideal for regular calibration, reducing uncertainty and supporting compliance with laboratory standards.

Q: When should the Didymium glass filter be utilized in a laboratory setting?

A: Use the filter during routine instrument calibration, after spectrophotometer repairs or maintenance, and as part of quality assurance protocols to verify ongoing wavelength and photometric accuracy.

Q: Where can the Didymium glass filter be sourced, and who commonly uses it?

A: The filter is available from manufacturers, suppliers, exporters, importers, and traders in India. It is commonly used by research laboratories, analytical facilities, and academic institutions that require precise spectrophotometer calibrations.

Q: What is the typical process for validating a spectrophotometer with this filter?

A: Insert the filter into the spectrophotometers sample compartment, scan across the visible spectrum (350 nm to 750 nm), and compare the instruments measured peak wavelengths with the filters certified peak values. Deviations indicate the need for instrument adjustment or servicing.

Q: Is the Didymium glass filter reusable, and how should it be cared for?

A: Yes, the filter is designed for repeated use under standard laboratory conditions. It should be stored in its protective case when not in use and cleaned gently with appropriate solvents to maintain its optical properties.
