BP460-35 Bandpass Filter - Fluorescence Microscopy (DAPI Emission)
Fluorescence Microscopy (DAPI Emission)
This filter is perfectly suited as an Emission Filter for the fluorophore DAPI, which is widely used to stain DNA in cells.
- How it works: DAPI is excited by UV light and emits a blue fluorescence centered around 461 nm. This filter allows the faint blue signal to pass to the camera while completely blocking the intense UV excitation light (thanks to the OD5 blocking).
Recommended Light Sources
- UV LED (365 nm)
- Mercury Arc Lamp
-
BP460-35 Bandpass Filter - Outdoor/High-Ambient Imaging
Machine Vision & Industrial Inspection - Outdoor/High-Ambient Imaging
The OD5 blocking ensures that sunlight or overhead factory lighting (which contains broad spectrum light) does not wash out the image; only the specific blue LED inspection light is seen.
Recommended Light Sources
- Blue LED (460 nm - 470 nm)
Fequently Asked Questions
Different Types of Filter Mountings
Unmounted:
- a bare glass optical filter
Mounted:
- Smooth Mount for protection of the optics. No thread is there on the mount.
Metric Mount:
- Start with M as prefix, usually seens as M25.5x0.5mm. Mostly used as camera filters
Imperial Mount:
- Start with SM as prefix, usually seen SM1, SM05 etc... Mostly used in Optical system. (You will have a SM external thread to connecting to other objects)
C-Mount:
- Very frequently used mounting. C-Mount is 1‘’-32TPI. And it is not the same thing as SM1, or M25.5x0.5mm.
What are the Thickness of the Optical Filters?
For Unmounted Optics:
- 0.5mm
- 1.1mm
- 2.0mm
*Most of our optics are coming with 1.1mm and 2.0mm
With Standard Mounting (Mounted, No Thread):
- 3.5mm (Default)
- 6mm (Upon Request)
Thread Mounted:
- 6mm - 8mm
