MidOpt LP Series Filter LP715
Uniforce Product
Salient Features
Near-IR Longpass Filter
Used with a monochrome camera to improve infrared contrast and resolution, LP715 filters block all visible light while passing Near – IR wavelengths. To block deeper infrared light we recommend our BP800 Bandpass filter – an effective choice when the filter material is 1mm thick or less.
LP715 Near-IR Longpass Filter
- Useful Range : 730-1100nm
- Cut-on Wavelength 50% T : 715nm
- Tolerance : +/- 10nm
- Minimum Peak Transmission : ≥90%
- Surface Quality : 40/20
The performance of a filter is based on what happens to light passing through the filter. The apparent color of light reflected off the surface is not a reliable way to judge the filter’s capabilities. Batch-to-batch difference in the apparent color of the coatings or filter substrates can often be easily seen when looking at two examples of the same filter type. The color of the coating does not indicate a disparity in performance.

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.
