• Description: no longer needed in my lab. I have not full information (only bandpass), but you may know enough of it given this information. Tests done with "mirror side" facing light source.

• Measures: Mount is exactly 1" 25,4mm (filter a bit smaller to fit in mount). Thickness is 0,246" (6,24mm).

• Catalog number and other info: D.O. #15-20260 NZS 5-6 (this last number might be the cut-on & cut-off tolerances in nm)

• Straight light-through behaviour (0º angle): LED & HALOGEN light source show light CYAN.

• Edge-on light-through behaviour through HALOGEN light source (around 80º angle): PURPLE color.

• Weight: 5,8gr.

• Condition: filter shows nice. No scratches or haze. I would say EXCELLENT OVERALL condition. Delivered in original package.

• Shipping: Remember I combine shipping. Ask for invoice (through) BEFORE paying if I didn't send it to you yet!)
