Hi Vik

I asked Asahi to make a new filter that I plan to use for
LO work, and it has now been received.
You'll find the details in attachment.
Could you add it to the usual page please?
http://www.vikdhillon.staff.shef.ac.uk/ultracam/filters/filters.html

Or do you prefer that we keep a separate page at NARIT?

I suggest to call this filter "N86" and I will prepare the
corresponding label for storage.

cheers
Andrea

Dear Dr. Richichi,
 
I found the package was delivered to the designated broker on
this Tuesday.
 
I will send the actual transmission data with electronic format.
The CWL is 861.1nm and FWHM is 12.2nm in collimated beam.
 
Monolithic RG695 colored glass was polished with 4.975mm
+/-0.025mm under the past instruction by Prof. Dhillon when we
produced Sloan filters for ULTRASPEC.
 
Thank you for choosing Asahi this time.
When you need another filter for NARIT in the future, we would
like to cooperate with you again.
 
Sincerely,
 
Toshihiko
