Greetings everyone,
The previous LD at my high school left unexpectedly some time ago, leaving me to cope with a collection of conventional instruments including around 20 or 30 old-style Colortran lekos. They appear to be largely the same as the newer 5-50 series, with the various lens positions. Most (presumably!) are equipped with 6x9 lenses, but some are marked as 6x12.
The musical coming up will require many of these instruments set to 40 degree field, which is not possible with a 6x12 lens.
I'm wondering if there's an easy way to tell the difference between a 6x12 lens and a 6x9, short of hanging the fixture and measuring the field.
Thanks to anyone who can help here.
