Yes. They are called Hydrogen Alpha (Ha) solar filters or complete Ha telescopes and they cost a lot more. The have a very narrow bandwitdh and typically require an f30 system hence the reduced aperture offered for existing systems. Small refractors are best for use with these filters.
Note the smaller the bandwidtgh the more you will pay but the better the surface contrast. However flares will be brighter with say a 0.8A filter compared to a 0.5A filter. A 0.7A is a good compromise.
