From t-kimura@asahi-spectra.co.jp Tue Sep 4 05:41:17 2007 Date: Tue, 4 Sep 2007 13:40:45 +0900 From: Toshihiko Kimura To: Mihalis Mathioudakis Cc: Vik Dhillon Subject: Measured data(NBF 3500A) Dear Dr.Mathioudakis, > The 350nm filters arrived today. How rapidly DHL has delivered ! > We would be grateful if the same code could be note on the rest of the > filters. Yes, I will keep it in mind. I will send you the actual transmission data of NBF 3500A. Regarding the filter number, the label on individual package shows filter name and the number, "No.1" "No.2". [Specifications] > CWL 351nm +/-1.5nm in collimated beam > => CWL 350nm +/-1.5nm in ULTRACAM's f/2.3 converging beam > FWHM 10nm +/-1.5nm in f/2.3 beam. > -Estimated peak transmission > 60% ? [Actual CWL] No.1 CWL 350.9nm FWHM 10.2nm in collimated beam => CWL 349.9nm in ULTRACAM's f/2.3 converging beam No.2 CWL 350.9nm FWHM 10.2nm in collimated beam => CWL 349.9nm in ULTRACAM's f/2.3 converging beam Fortunately, both filters have perfect center wavelength. Peak transmittance exceeds 75%. I hope the filter will be able to help your research.
