Cedar wood oil
A high-quality microscope objective lens with a specialized coating is typically used for oil immersion microscopy. The lens is designed to work with a specific type of oil (usually immersion oil) to enhance resolution and numerical aperture by reducing light loss due to refraction. Oil immersion microscopy is commonly used for high-magnification studies requiring precise imaging, such as in medical or biological research.
Oil immersion is used to minimize light refraction and increase resolution by eliminating the air gap between the lens and the specimen. The oil has a refractive index close to that of glass, allowing more light to enter the lens and improving the quality of the image.
If you are using the oil immersion objective on a microscope, you must use oil to increase the resolution of the lens. These lens are used at very high magnification.
Non-essential oils are oils that are not considered essential oils, which are concentrated plant extracts typically used in aromatherapy. Non-essential oils can refer to cooking oils such as olive oil, coconut oil, or vegetable oil that are not part of the essential oils category.
immersion oil
Liquid paraffin is a preffered immersion oil because althogh having a lower RI than cedar oil it is less likely to result in damage to the objective lens. Synthetic oils have better characteristics but are expensive.
Carrier oils are neutral (and non-toxic) oils used to dilute and deliver essential oils. Common carrier oils for use with dry or sensitive skin include: almond oil, olive oil, palm oil, & peanut oil. Common carrier oils for normal skin include jojoba oil, sesame oil, and soybean oil. Common carrier oils for oily skin include: grape seed oil, sunflower oil and walnut oil.
Some examples of neutral oils that can be used in cooking and baking include canola oil, grapeseed oil, and vegetable oil. These oils have a mild flavor and are versatile for various culinary applications.

Oil immersion objectives are used in microscopes to increase the resolution of the image by reducing the refraction of light as it passes from the glass slide to the objective lens, minimizing distortion and increasing clarity. The higher refractive index of the oil (typically immersion oil with a refractive index of 1.515) helps to capture more light and reduce scattering, resulting in a sharper image. Oil immersion objectives are typically used with high numerical aperture lenses for maximum resolution in microscopy.
Coconut oil, Palm oil, and Palm Kernel oil
There are several different oils used in an airplane. Engine oil, fuel oil, hydraulic oil etc.
