Product Description & Reviews

Suggestions for Use Holmium presents a wide range of crisply resolvable peaks which are easily used to correlate the wavelength indicator on your spectrophotometer to the known Holmium peaks. The initial procedure should be to scan the filter over the useable range to assure that all of the peaks can be resolved. Alter the slit width and scan rate to produce a useable spectra. Check each peak to assure that the reading on your spectrophotometer is within the manufacturer's tolerances for the wavelength of your spectrophotometer. If not, have a service technician check and, if necessary, adjust your instrument. Holmium is measured against an air blank. Product Description Holmium has been used as a wavelength reference for many years and like its liquid counterpart, the holmium glass filter produces characteristic peaks that make it suitable for use as a wavelength reference. As a solid reference material, the holmium glass filter is more robust than the liquid cell as it is mounted in an anodized aluminum housing to offer greater protection. Holmium offers sharp, stable peaks over the range of 240 nm to 640 nm. The holmium reference is used to assure that the wavelength scale of your instrument is within the manufacturers tolerances to the actual wavelength being measured. The use of the holmium glass reference filter assures that the optical configuration of your quality control is exactly the same as for a normal analysis. Package Included: 1PCS 12.5mmx45mmx1.0 mm 240-640nm Holmium Glass filter

Features & Highlights

  • Periodically check the spectra, at a minimum in the area where you are doing your analysis. The periodic use of your Holmium cell will build a log of your instrument's.wavelength accuracy for use with certification and troubleshooting should the correlation change over time.
  • Interpretation of Results Consult your spectrophotometer's reference manual for the specification of your instrument's wavelength scale tolerance. This figure will be listed as a plus and minus (+/-) number in nanometers (nm).
  • Add your instrument's wavelength tolerance to the confidence limit on the certificate supplied with the Holmium wavelength reference. Compare the peak wavelength values measured on your instrument with the expected values calculated from your instrument mannual and the NIST traceable certificate.
  • If the readings are within the expected range for your instrument, then your wavelength scale is correct. If not, consult your service technician and have your instrument evaluated.
  • We are welcome you customize your size according to your need, any size and any wavelength is no problem.Pls kindly contact us via amazon or skype:ydm810921 at any time!

The B+W 093 Infrared Filter blocks the entire visible spectrum and so to our eyes looks completely opaque. Unlike the 092 filter, it makes pure infrared photography possible by eliminating the visible spectrum. Its transmission only begins to exceed 1% at 800 nm, rising to 88% at 900 nm, and remains that high far beyond the upper limit of sensitization covered by infrared films. This filter results in dramatic loss of effective ISO, but in the scientific field, materials research, and

mpn: Y1IR72086, ean: 0024066053787,
The Hoya R72 Infrared filter is specifically designed for infrared photography with digital cameras and infrared film. Infrared light starts in the high-red area of the visible spectrum at around 750nm and goes up beyond 1000nm. This light is not visible to the naked eye. Looking through the R72 filter it looks almost opaque because the filter is only passing light from the very high red edge of the visible spectrum and infrared light. Infrared photography yields very interesting, sometimes
