Summary
This study introduces a normalized Delano diagram for optical systems. This normalization simplifies analysis of optical system parameters like distances and angles, aiding in optical design.
Area of Science:
- Optical Engineering
- Geometric Optics
- Optical Design
Background:
- The Delano diagram is a graphical tool used in optical design.
- Standard Delano diagrams can be complex to interpret due to varying system parameters.
Purpose of the Study:
- To propose a novel normalization method for the Delano y, ŷ diagram.
- To simplify the analysis and comparison of different optical systems.
Main Methods:
- Normalization of y heights by entrance pupil height and ŷ heights by image height.
- Expressing normalization constants in terms of system parameters.
Main Results:
- Reduced distances normalized by focal length.
- Marginal ray angles normalized by numerical aperture.
- Chief ray angles normalized by field aperture.
- System powers normalized by total system power.
Conclusions:
- The proposed normalization is invariant under refractions and transfers.
- A stop or conjugate shift necessitates renormalization.
- This method enhances the utility of the Delano diagram for optical system analysis.

01:18pV-Diagrams
The pV diagram, which is a graph of pressure versus volume of the gas under study, is helpful in describing certain aspects of the substance. When the substance behaves like an ideal gas, the ideal gas equation describes the relationship between its pressure and volume. On a pV diagram, it is common to plot an isotherm, which is a curve showing p as a function of V with the number of molecules and the temperature fixed. Then, for an ideal gas, the product of the pressure of the gas and its...
01:21Cell Diagrams and IUPAC Conventions
Electrochemical cell notation is a standardized symbolic representation that communicates the structure and reaction pathway of galvanic and electrolytic cells. This notation plays a critical role in describing redox reactions and electrochemical cell configurations without the need for detailed diagrams.In electrochemical cell notation, a single vertical line “|” denotes a phase boundary, such as between a solid electrode and an aqueous solution. A double vertical line “||” represents a salt...
01:12Bewley Lattice Diagram
The Bewley lattice diagram, developed by L. V. Bewley, effectively organizes the reflections occurring during transmission-line transients. It visually represents how voltage waves propagate and reflect within a transmission line, making it easier to understand the complex interactions that occur.

Different notations are used to represent the three-dimensional structure of molecules on two-dimensional surfaces. One of the most commonly used representations is the dash-wedge formula. The dashed wedges, solid wedges, and the plane lines indicate the groups situated behind the plane, coming out of the plane, and in the plane, respectively.
The organic molecules rotate across the single bonds leading to numerous temporary three-dimensional structures of varying energy known as conformers.

01:07Ladder Diagrams: Complexation Equilibria
Ladder diagrams are useful for evaluating equilibria involving metal-ligand complexes. The vertical scale of the ladder diagram represents the concentration of unreacted or free ligand, pL. The horizontal lines on the scale depict the log of stepwise formation constants for metal-ligand complexes and indicate the dominant species in all the regions.
The formation constant, K1, for the formation of Cd(NH3)2+ complex from cadmium and ammonia is 3.55 × 102. Log K1 (i.e. pNH3) is 2.55, and...

02:39Phase Diagrams
A phase diagram combines plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance. These diagrams indicate the physical states that exist under specific conditions of pressure and temperature and also provide the pressure dependence of the phase-transition temperatures (melting points, sublimation points, boiling points). Regions or areas labeled solid, liquid, and gas represent single phases, while lines or curves represent...
