Aiming at a 12" steel plate, I have the problem of the IR laser blooming so much it obscures the entire target.
I have a TLR VIR II on a pistol, and a Holosun LS321R on a rifle. Both have the same problem. I just want a laser that I can pinpoint on the target, not one that is massively bright. Is the issue that these lasers are just low-end??? The NV is a green PVS-14. |

Can't you put a filter on the ir ?
Have you tried different nm ? |

It's not that the lasers are low end, it's that there's too many milliwatts for the laser not to bloom.
I had a Steiner dbal I2 and they sell a neutral density filter for them that cut way down on the bloom. Unfortunately I don't think they have one for the Holosun. You could get the actual neutral density lens and have someone 3d print a fixture that would work with your laser though. |

Pretty normal.
Going to bloom less on a paper/cardboard target. If shooting steels you can kinda move the aiming point around a bit to help confirm via the bloom that you are on target. |

Are you using just the IR pointer? If so, try using it in conjunction with the IR illuminator. Often times, the additional light energy surrounding the pointer will "tone down" the bloom effect.

Years ago there was a way to make a filter out of 35mm color film leader. (The part that hangs out of the can an is exposed to light)
They would punch out a circle with a hole punch and fix over a red laser to make them so weak they would be equal to a IR laser, you may need to use more than one I bet it would work to on IR laser to weaken it by installing some film leader in a small scope flip cover with a hole drilled in the center so you could open it and get full power when needed eBay has them as small as 25.5 mm. And you may get smaller with some looking |

Lasers will bloom without supplemental IR. Using a stronger IR illuminator will keep it from blooming.
Or as some have mentioned try a filter. Doesn't have to be expensive. I've made filters out of house hold materials before to get by. |

Doesn't have to be expensive. I've made filters out of house hold materials before to get by. This. IR LUM to mitigate helps a ton. Power of the laser itself is the main root cause of course. Even a Class 1 .7mW will bloom at distance. This is why we made our Tor Mini with a selectable power output at .2mW, .4mW and .7mW. Not bad for 115 bones. |

No Chinese counter can match the price nor the capabilities.

Would love to help you out, I had the same issues with my perst, and I 3d printed a solution for which I now sell on ebay
/itm/125116608112 Post some pics of the aperture and the dimensions and we'll see what we can come up with! I might even be tempted to buy a holosun and return it once I make it

What are your specs on your tube?

Quote HistoryOriginally Posted By DirtyHandsRob: What are your specs on your tube? That was going to be my question. The halo value has a considerable effect on bloom. I know I have posted these photos before, but hopefully it reiterates the point  Attached File Attached FileThose are both high end image tubes with a very good/low halo value. An older surplus thin Filmed tube with higher halo would be an even more dramatic difference in bloom/halo. On devices like a peq15, neutral density filters applied to the pointer will help reduce the power of the pointer and give a much finer aiming point. |

Horrible Aim on your part (get it?  )But very edgy post nonetheless |

He mentioned rifles specifically in which case size is less of a factor The TLR VIR II would work great for both pistol/rifle. The illuminator is floody but will help minimize bloom. For a tighter beam, add the focus ring that Darq makes. The battery choice, on/off indicator, and momentary activation are all better than the Tor IMO |

Yea, I'm willing to bet the halo spec is affecting what you're seeing.
Do you have access to another NVG so you can compare the images? I remember using a lower spec mono and I could tell the bloom was significantly worse on that tube than a much better tube. Yard lights bloomed quite considerably. |

Cheap lasers have beam divergence issues.
