What's the actual size of your 2" filters in "mm" with and without frame/ring? What step down adapter is suggested from a 52 mm to "-- mm"?

What are the threads and pitch of your 1.25" and 2" filters?

Frage von: Anders G. am 20.09.2017 12:55:00 | 1 Antwort(en)

Our 1.25" filters have a M28.5 male (and M28.5 front female) thread / our 2" filters have a M48 male (and M48 front female) thread

Both thread sizes come with our proprietary pitch - which is not the same for the female and male threads.
This is our own proprietary "emergency solution" for uniting a world were manufacturers all over the world copy from each other - to the point that there are almost a dozen different pitches in use for male and female threads. Traditionally US-companies used to do a UNF-based pitch and the rest of the world went for metric threads - but these do vary from 0.5 to 0.75.

For this reason it does not make sense to publish our non standard pitch because our pitch is made to cope with all existing metric and US-pitch standards - and as said - our solution has evolved from sheer necessity. It is a mixture of a queer pitch and under-/over-dimensioning . We will not want to declare this as a standard and get bashed up for it. It works for us and is a result of 20 years adaptation to fit our filters onto all crazy threads we have seen. And inspite of this - every now and then there comes another "dragonboat-eyepiece" were even our filters may not fit...

Sie müssen eingeloggt sein um Fragen zu beantworten.

Welche Größe (Durchmesser) darf ein Filter-Einsatz haben, den man in Ihre 2"-Filterfassung (#2459252) einbauen kann? Kann ich da eine "Scheibe" mit 50mm Durchmesser einbauen (bspw. https://www.edmundoptics.de/optics/optical-filters/bandpass-filters/589nm-cwl-10nm-fwhm-50mm-mounted-diameter-/)? Oder wie muss der Filter aussehen, der in die Fassung passt?

Beste Grüße,
