When Lunt Solar started making solar telescopes and filters, the subject of eye safety was at the forefront of design. Our designs were approved by a senior ophthalmologist professor at a leading University of Ophthalmology in Canada. A safety criteria was determined for both UV and IR transmission. This criteria basically set the bar at less than 1×10-5 (T) for any hazardous radiation.\u003c\/p\u003e\n\u003cp\u003eSeveral standalone filters in Lunt products meet this criteria as a single unit. However, Lunt sets double and sometime triple standards for this requirement so that in the unlikely event one filter fails, the user will still be protected.\u003c\/p\u003e\n\u003ch3\u003eOur Filters\u003c\/h3\u003e\n\u003cp\u003eEnergy Rejection Filter – The filtering of a Lunt system starts with a “true” energy rejection filter at the front of the system. This filter is unique to Lunt, and blocks both dangerous UV and IR. On smaller telescopes the ER filter is seen as a red looking filter installed at a slight angle (to remove internal ghosting). This is either installed at the front of the scope or just inside the main objective. On larger aperture telescopes, Lunt puts an additional IR blocking filter onto the front surface of the main objective. This will remove all heat load from the internal parts. Even on these large aperture systems we still provide the secondary red ERF just inside the objective.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEtalon\u003c\/strong\u003e – The next “filter” in the system is actually the etalon. The etalon was not designed as a safety filter however, it does have a very highly reflective surface that rejects most UV (T). Significantly, this would reject the majority of all IR if no prior IR filters were present.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBG Filter\u003c\/strong\u003e – The third filter is the Schott-designed BG (Blue Glass) filter.

Inside the diagonal is a Long Wave Pass filter. To begin with, it is designed to reflect a specific percentage of the 656nm wavelength. It sits at a 90 degrees angle and pass thru IR into the backing plate.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBlocking Filter\u003c\/strong\u003e – The next filter is the blocking filter.

The multitude of safety features we employ insures that our customers will be protected. They are protected even if they use our products improperly.

Our coating facility has the required ability to produce AR coating at less than 0.1%R (typically in the 0.06%R range). They also hold the high reflector coatings to better than +\/-1%. The ability to control the coating processes to such high accuracy has allowed us to make precision modifications to the coating formulas, which have proven to increase contrast through the reduction of background noise.\u003c\/p\u003e\n\u003ch3\u003eQuality Assurance\u003c\/h3\u003e\n\u003cp\u003eEach coating batch is provided with full scans of the coating applied and is certified to meet any and all safety requirements.

The 8mm (44x) pushes in tight on active regions when seeing cooperates. The 12mm (29x) is your all-purpose solar eyepiece — enough magnification for surface detail with enough field to keep context. The 16mm (22x) pulls back for full-disk views and prominence surveys along the limb. All three feature 60° apparent fields and 0.1% AR coatings, minimising ghost reflections in the narrow-band optical path.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat You'll See\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEverything the LS50THa reveals at 0.6Å bandpass, now with the magnification range to explore it all. At 44x through the 8mm eyepiece, active regions resolve into intricate structures of light and dark, and prominence detail sharpens from soft arcs into defined loops and threads. At 22x through the 16mm, the full solar disk fills the field with context — survey the entire limb for prominence activity, trace filament paths across the hemisphere, and watch the slow evolution of active regions over the course of a session. Doppler True pressure tuning remains your most powerful tool. Scan through the chromosphere at any magnification. Watch structures appear and recede as you shift through the hydrogen-alpha line.

The B1200's 12mm clear aperture ensures the full image circle reaches your camera without vignetting at focal lengths up to 1,200mm. Visually, the zoom eyepiece transforms the observing experience. Scan the full disk at low power to survey prominence activity and filament structure, then twist to higher magnification and resolve individual features in real time. No eyepiece swaps, no refocusing, no missed moments of good seeing.

The B1200 is the blocking filter that serious solar imagers choose: 12mm of clear aperture means your sensor sees the full unvignetted image circle. The zoom eyepiece is a genuine game-changer for solar sessions. Conditions change, targets move, and active regions evolve. Continuous magnification adjustment without changing glass means you are always at the right power for what is happening on the Sun.
