248.6 nm MaxLine® laser clean-up filter
Part Number: LL01-248-25
• Your filter spectrum may differ slightly from the typical spectrum above, but is certified to meet the optical specifications noted below.
248.6 nm MaxLine® laser clean-up filter
MaxLine laser-line filters transmit greater than 90% of the light at a precisely defined laser line, while offering incredibly steep edges to
eliminate optical noise from non-lasing (plasma) lines and spontaneous emission.
