IDAS LPS filter were first designed as LPS-P1 in 1999. This was the industry-first multi-bandpass technology coating and really advanced design and concept that time, but isn’t obsolete even today at all. This must be still best as a broadband filter in the market. Several thousands high-end customers are currently using all over the world to improve their image under the light-polluted sky. I’m proud of providing this kind of premium quality filter into our community.
Also keep in mind, we have never had the quality issue from the beginning of the business. Nil!! That’s amazing. And all productions are so consistent in quality and performance. Very well controlled at Japanese factory all the time. I’m proud of that too! Thank you so much, IDAS and Aonuma san.
Now IDAS, a pioneer of the advanced filters, has made an another milestone in our industry, called LPS-D2. This new member of LPS family effectively suppresses high pressure sodium vapor lines and white LED spectrum. See following response curves for how the D2 filter specifically targets the wavelengths from LED lights.
White LED is a new monster we, astronomers have to fight with. This is IDAS answer. This should be an another industry-first astronomical filter considered for the modern light pollution – white LED. You can see how LPS-D2 is blocking white LED spectrum.
One extra benefit is this filter reduces blue cast.
Buy risk-free: When it’s time to trade up you’ll get the most value for your used gear.
