OPTOLONG 1.25" UV/IR Cut Blocker Filter Astronomical Telescope Filters for Deep Sky and Planetary Photography
- Application: Camping
Precise details:
Introduction:
UV/IR Cut filters are IR and UV cut-off filters for astronomical photography, which can effectively prevent interference from IR and UV rays and provide focus and dust protection. UV-IR filters are used in all digital cameras, CCD cameras and webcams for photo processing technology. High transmittance visual band (420 nm ~ 680 nm), including H-Alpha (656 nm), S-II (672 nm) and NII lights. They are used to concentrate light and protect against dust.

The main uses and real shot effect diagram (uses):
1, Suitable for use with DSLR and CCD, can effectively inhibit the interference of UV and IR
2, For astronomy photography inside with monochrome CCD use
3, For DSLR conversion for astrophotography
Manufacture:
- Optical high precision double-sided polishing to ensure parallelism greater than 30" and high flatness 1/4λ to avoid halos.
- Precision double-sided optical coating, not a two-piece bonding type, effectively increases transmittance and cut-off depth.
- Electron Evaporation Technology
- Ion Source Assisted Coating (IAD) technology, which increases the density of the film layer and ensures that the temperature drift of the filter wavelength due to temperature is minimized.
-High uniformity planetary wheel coating fixture to improve filter wavelength uniformity.
Metal frame:
Thread: M48*0.75
High quality aircraft aluminum
Precision CNC one-piece molding

Sizing & Fit Guide
Please be aware that most of our clothing is Juniors' sizing, which runs smaller than regular US / European Women sizing. Refer to the measurements chart for each individual product to determine the best size for you. Product specific size chart and information can be found in product description or in product picture gallery.
Our team does it's best to include accurate size details and measurement of each item in the product descriptions. If you have questions regarding sizing or any other information on a specific item, please email us at support@mrslm.com for specific details.
Find the best size
When comparing your measurements to those listed on the site, make sure to check if the fabric is stretchy or not. If it is, it can stretch an inch or more.
- Bust: Wrap the measuring tape loosely around the fullest part of your bust to ensure a comfortable fit.
- Waist: Measure the narrowest part of your natural waist, holding the measuring tape loose enough to fit comfortably.
- Hips: Drape the measuring tape around the widest part of your hips, resting the tape comfortably against your body.
- Length: For tops and dresses, measure from the top of your shoulder to the hem. For strapless dresses, measure from the highest part of the neckline to the hem. For pants and skirts, measure from the top of the waist to the hem.
- Sleeve: With your arm outstretched, measure from the base of your neck to the end of the sleeve hem to determine where the sleeve length will fall on you.
