On request we will gladly send you a current price list or if you want we will tell you the price of individual products. When ordering from Hellma we will need to know a few things. Please check the following list when making out your order to make sure you have included all information:

• the catalogue number
  
• the type of material
  
• the light path
  
• the centre height
  
• the quantity required
  
• transmission matching requirements
  
• polarimetric certification requirements
  
• antireflection or reflective coatings, if required
  
• Verspiegelung
  
• type of packaging required (standard packaging or a separate case)

Within the scope of technical possibilities we will be pleased to make specially designed cells and immersion probes according to your needs and specifications. For price reasons we endeavour to use standard cells or probes as the basis for these whenever possible.

If you are interested in special designs please send us a technical drawing. Before manufacture commences, you will then receive a drawing from Hellma and once you acknowledge approval, this drawing will serve as an agreed specification for manufacture.

Provided it is economically viable and technically possible, repairing cells and immersion probes is a part of the service we offer. If you want to have a cell or an immersion probe repaired simply send it to us. Where feasible, Hellma will then quote for its repair.
