In the field of dentistry, dentists and clinicians have to work on a small dark hole of a tooth or even smaller object which requires precision and steadiness of hands. With the advancement of technology, now dentists are equipped with dental loupes that reduces the eyestrain and enables efficiency in the work.
Dental Loupes assures clinically improved results. A dentist can easily diagnose small tooth fractures; detect a cavity or an open margin of the crown. Besides, wearing loupes for magnification helps to improve precision in the treatment and increases the chances of positive outcomes.
Furthermore, dental loupes also improve ergonomics, deterring dentists from bending towards the patient, which causes back pain, neck pain and eye strain.
A dental loupe comes with two different lenses, i.e. Galilean lens and Prismatic lens. In the following blog, we will discuss some of the critical differences between the two lenses to help you make a better purchase.
What are Galilean Loupes?
Surgical Loupes in Galilean style consist of two lenses – convex objective lens and concave eyepiece lens. Both the lenses in a pair of loupes work efficiently to deliver higher magnification and clear image than compared to single-lens loupes. Besides, Galilean loupes offer a superior depth of field and wider width of field. Galilean loupes come in a different range of magnification. It is ideal for people associated with dentistry, ophthalmology and for surgeons due to its affordability and lightweight design.
What are Prismatic Loupes?
Prismatic Loupes are also known as Keplerian loupes. It provides edge to edge clarity and higher magnification. They consist of two or more positive convex lenses. Prismatic loupes are laser aligned and treated with anti-reflective coating to produce superior vision.
What are the key differences between Galilean and Prismatic Loupes?
Galilean Loupes – They consist of two lens telescopes. They provide lower magnification with reduced field-of-view compared to Prismatic loupes.
Galilean loupes usually feature lower magnification (2x-3x). Additionally, the 3x Galilean Loupe offers an 8-degree field of view, and 3x wide loupe offers an 11-degree field of view.
Prismatic Loupes- These types of loupes have a more complex design and includes a prism between the lenses, which reflects and magnifies without reducing field of view.
Prismatic loupe features higher magnification (3.5x-6x). Additionally, the simple 3x loupe offers a 14-15 degree field of view.
Galilean Loupes- These loupes feature two lenses -one is higher power objectives lenses grouped with positive power, and the eyepiece grouped with negative power. The combination of positive and negative power of lenses in the loupe allows it to produce a clear image compared to magnifying glasses.
Prismatic Loupes – These loupes feature objective lenses and eyepiece lenses, all of which are positive in power. A prism between the lenses enables high optics, fields the light, thereby increasing magnification without significantly increasing the size of the lens barrel and expansion of the loupe length.
Galilean Loupes – For first time users, Galilean lenses are the best option. There are two reasons for that- Galilean lenses have lower magnification than prismatic lenses which helps the first time user to adapt his/her brain with the loupe vision. Secondly, the Galilean lenses are comfortable to wear in terms of field of view and line of sight. With fewer adjustments, Galilean loupes can effectively be used for magnification.
Prism Loupes - To optimise the use of modern prism loupes, you must have a line of sight directly through the centre of ocular
Galilean Loupes - These types of Loupes allow two simple adjustments – Individual adjustment of interpupillary distance and the angle view.
Prismatic Loupes – These loupes allow customisable setting which promotes right posture without affecting viewing angle.
Galilean Loupes – Generally, the Galilean loupes are light in weight and compact in size due to their simple design. They provide a bright picture but offer a narrow field of view, reducing the clarity from the edges.
Prismatic Loupes – They are long, heavier as they use complex design and incorporate prism between the lenses, which otherwise produces an inverted image.
Prismatic lenses offer a larger field of view, double than the Galilean lens. But due to more optical components, they offer less bright images.
Dental Loupes are built to ease the job of the dentists by providing enhanced magnification. Both Galilean and Prismatic do the same work. The only major difference is in the level of magnification. So, one should choose the loupe depending on the nature of their job and required magnification. However, for the first time user, Galilean loupes are recommended.
Schultz offers best dental loupes both in Galilean and Prismatic lenses which are made using high optic lenses that only provide high-grade vision but are comfortable to wear all day. We offer a wide range of trendy and stylish loupes at attractive rates.
