MidOpt BP Series Filter BP540
Uniforce Product
Salient Features
BP540 (Limited Availability)
BP540 filter material is designed for use with green LED lighting. MidOpt StablEDGE™ optical filters are specifically designed to be less susceptible to effects from angular shifting seen when optical filters are placed in front of short focal length (<12 mm) camera lenses.
StablEDGE™ filters take advantage of absorptive filter glass to form the leading
edge of the filter passband.This assures no shifting in this region, even when the
lens FOV exceeds 100°.StablEDGE™ designs are less angle-of-incidence sensitive, inherently more rugged, and are environmentally stable.

Available Mounts
Threaded Mount
- Designed for lenses with filter threads, a variety of filter types and stock threaded sizes are available: M13.25-M105
- Larger sizes, 62mm to 105mm, are made to order and are not returnable
- Custom thread sizes are available upon request.
- Threaded mounts are available as black anodized aluminum rings. Rotating mounts with locking thumb screws are generally provided.
Ordering Example:
- Filter: BP470
- Mount Size: M27
Correct Part# is:
- BP470-27

Slip Mount
- Designed for varifocal lenses, wide angle lenses and lenses without filter threads
- Accommodates standard threaded mounts
- Low profile and oversize diameter design prevents wide angle lens vignetting
- Locking set screws and a wrench are provided to secure the adapter to the lens
- Many varifocal and shorter fixed focal length (wide angle) lenses are not supplied with filter threads due to the presence of a protruding, strongly convex lens element. Our slip mount adapters allow standard threaded filters to be fitted securely to these and a large variety of lenses that do not have filter threads provided.
Ordering Example:
- Filter: BP470
- Outside Diameter of Lens in mm: 43mm
Correct Part# is:
- BP470-S43

C/CS Camera Mount
- Designed to thread directly into any C/CS mount camera between the lens and sensor
- Wrenching slots aid in threading the filter into the camera body. A wrench is supplied with each filter.
- Helpful in applications with space constraints
- Can be used with wide angle lenses that do not accept filters at the front end to prevent vignetting
- C/CS mount filters are available in a standard 1mm thickness
Ordering Example:
- Filter: BP470
- Mount Size: 25.4
Correct Part# is:
- BP470-25.4

Unmounted & Custom Size
- Any MidOpt filter type can be provided as an Unmounted filter
- Custom shapes and sizes are typically fabricated with one day to two week lead times
- Custom filter types with longer lead times can also be quoted. Please contact us regarding feasibility.
